4-Channel And 6-Channel High Speed,
Auto-direction Sensing Logic Level
Translators
Features
The ISL3034E, ISL3035E, ISL3036E 4- and 6-channel
bi-directional, auto-direction sensing, level translators
provide the required level shifting in multi-voltage systems at
data transfer rates up to 100Mbps. The auto-direction
sensing feature makes the ISL3034E, ISL3035E, ISL3036E
ideally suited for memory-card level translation (or for
generic four to six channel level translation) especially if
bit-by-bit direction control is desired. The VCC and VL supply
voltages set the logic levels on either side of the device.
Logic signals present on the IC’s VL side appear as higher
voltage logic signals on the IC’s VCC side and vice versa.
The ISL3035E features a CLK_RET output that returns the
same clock signal applied to the CLK_VL input, but with
timing that mimics the data returning from the I/OVCC inputs.
• 100Mbps Guaranteed Data Rate
The ISL3034E, ISL3035E, ISL3036E operate at full speed
with external input drivers that source as little as 4mA output
current. Each I/O channel is pulled up to VCC or VL by an
internal 30µA current source, allowing the ISL3034E,
ISL3035E, ISL3036E to be driven by either push-pull or
open-drain drivers.
The ISL3034E and ISL3036E include an enable (EN) input
that when driven low places the IC into a low-power
shutdown mode, with all I/O lines tri-stated. All versions
feature an automatic shutdown mode, that places the part in
the same shutdown state when VCC is less than VL. The
states of I/OVCC and I/OVL during shutdown are chosen by
selecting the appropriate product (see Table 1).
The ISL3034E, ISL3035E, ISL3036E operate with VCC
voltages from +2.2V to +3.6V and VL voltages from +1.35V
to +3.2V, making them ideal for data transfer between
low-voltage microcontrollers or ASICs and higher voltage
components.

NOTES:
6. VL must be less than or equal to VCC - 0.2V during normal operation. However, VL can be greater than VCC during start-up and shutdown
conditions and the part will not latch-up nor be damaged.
7. Input thresholds are referenced to the boost circuit.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
9. Delta between all I/OVL channel prop delays, or delta between all I/OVCC channel prop delays, all channels tested at the same test conditions.

Application Information
VL
Overview
The ISL3034E, ISL3035E, ISL3036E are 100Mbps,
bi-directional voltage level translating ICs for multi-supply
voltage systems. These products shift lower voltage levels
on one interface side (supplied by VL) to a higher voltage
level on the other interface side (supplied by VCC), or vice
versa. VOH of the I/OVL pins tracks the VL supply, while VOH
of the I/OVCC pins tracks the VCC supply.
These ICs feature bit-by-bit auto-direction sensing to
increase flexibility, and to eliminate the need for direction
control pins. On chip pull-up current sources in the active
mode, and pull-up resistors in SHDN mode, eliminate the
need for most external bus resistors. Drivers interfacing with
these level translators may be open-drain or push-pull types,
and all three versions may also be used for unidirectional
level shifting.
The three versions share the same architecture, but the
ISL3034E is a general purpose 6-Channel version, while the
6-Channel ISL3035E specifically targets SD Card and other
memory card applications. The 4-channel ISL3036 targets
nibble and byte based applications, as well as 4-wire SPI
interfaces. Power supply ranges allow level shifting between
1.5V, 1.8V, and 2.5V powered devices on the VL side to
2.5V, and 3.3V devices on the VCC side.
Principles of Operation
When enabled, these level shifters detect transitions on an
I/O pin, and drive the appropriate logic level on the
corresponding I/O pin on the other “side”. If the transition
was low-to-high, the channel shifts the voltage up to VCC (for
transitions on an I/OVL pin) or down to VL (for transitions on
an I/OVCC pin), and then drives the shifted level on the other
side. The ISL3035E enables whenever VCC > VL + 200mV,
while the ISL3034E and ISL3036E enable if EN = 1 AND
VCC > VL + 200mV.
Upon detecting a transition on either I/O pin, that channel’s
accelerator circuitry actively drives the opposite side’s
(output) pin to GND or the output’s supply rail, and then turns
off. Weak hold circuitry then maintains the logic state until
the input is 3-stated, or until another active transition occurs
on either I/O pin for that channel. Figure 5 shows the
simplified block diagram of one level shifting channel. The
accelerator circuitry comprises high and low threshold
detectors, one shots with level shifters and large output
drivers. A transition on one of the I/OVL or I/OVCC pins
momentarily defines that pin as an input. When the high or
low threshold is crossed, a one-shot fires either the PMOS or
NMOS driver, respectively, on the opposite side (effectively
the output). These drivers are large enough to quickly drive
the output node to its respective supply or to GND. Note that
this transition on the “output” trips the transition detector on
that pin, firing its accelerator, which feeds back to the “input”
to help reinforce slow transitions, such as those from an

open-drain type driver. Once the one-shot - and thus the
accelerator - times out (approximately 3ns to 4ns), the large
output drivers tri-state and the pins are weakly held in the
last state by the small NMOS transistor between I/OVL and
I/OVCC (for a low) or by the small current sources (for a
high). In this static state, the I/O pins are easily overdriven by
the next transition from an external driver. Having large
pull-up and pull-down devices in the accelerator (vs just an
active pull-up) nearly eliminates the concern about the
external driver’s output impedance, and that impedance’s
effect on VOL, fall times and data rate.
The weak pull-up current sources on each I/O pin and the
NMOS pass transistors, remain ON whenever the IC is
enabled. If a channel’s external driver tri-states, the weak
pull-up currents either keep the I/O pins high, or if the last
state was a low the current sources pull the I/O pins high. In
the latter case, each channel’s accelerators will once again
fire when either the I/OVL or the I/OVCC voltage crosses the
accelerator’s high threshold level.
Auto Direction Sensing
Each level translator channel independently and
automatically determines the direction of data transfer
without any external control signals. As described earlier, a
transition on either of the channel’s I/O pins momentarily
defines that pin as an input, which then translates and drives
that input signal to the channel’s corresponding pin on the
other port (now the output). After a brief period of active
driving, both I/O pins return to their weak “hold” mode, where
the next transition on either I/O pin determines the direction
for the next transfer.
Auto sensing saves valuable processor GPIO pins (three
[CLK, CMD, DAT] for SD Card applications, or six for the
general purpose hex case), and simplifies the software
associated with the peripheral interface.
Using Open Drain Drivers
These level translators’ accelerator based architecture
works equally well when driven by push-pull or open drain
type drivers (e.g., for the CMD line initialization in MMC
FN6492.0
March 31, 2009
ISL3034E, ISL3035E, ISL3036E
applications). The low static pull-up current is easily
overdriven by an active pull-down, and the feedback nature
of the accelerators (i.e., the accelerator firing in one direction
also triggers the accelerator in the opposite direction) aids
the passive pull-up once the input signal passes the
accelerator’s high threshold. The pull-up current and load
capacitance set the input signal rise time, and thus the
maximum data rate. For slow data rates the internal pull-up
current may suffice, but higher data rates - or more heavily
loaded signal lines - may require an external pull-up resistor.
Using External Bus Resistors
As mentioned earlier, these level translators incorporate I/O
pin pull-up current sources when enabled, and I/O pin
pull-up resistors in SHDN (except for the ISL3035E’s I/OVCC
pins). Therefore, external pull-up or pull-down resistors
shouldn’t be necessary, and aren’t recommended, unless
using high-speed open drain signaling.

pull-ups on the I/OVCC and I/OVL pins.

WIDE SUPPLY RANGE
These ICs operate from a wide range of supply voltages.
VL is designed to connect to the supply of 1.5V, 1.8V, and
2.5V powered devices, while VCC is targeted for 2.5V, and
3.3V components. Remember that VCC must be greater
than VL for proper operation.
POWER SUPPLY SEQUENCING
Either VCC or VL may be powered up first, but the IC
remains in SHDN until VCC exceeds VL by as much as
200mV. VL may exceed VCC by as much as 4V without
causing any damage.
I/O PIN INPUT THRESHOLDS VS SUPPLY VOLTAGE
Even though the “Electrical Specification” table on page 4
shows the I/O pin input thresholds (VIH, VIL) with a fixed
delta from the supplies or GND, the thresholds are better
represented as a percentage of the supplies. The typical
I/OVCC and CLK_VCC VIH runs about 55% to 60% of VCC,
while the corresponding VIL runs about 33% of VCC. The
typical I/OVL and CLK_VL VIH runs about 60% to 70% of VL,
while the corresponding VIL runs about 25% to 35% of VL.
Low Power SHDN Mode
This family of level translators features a low power SHDN
mode that tri-states all the I/O and output pins, considerably
reduces current consumption, and enables any pull-up
resistors on a port’s I/O pins (see Table 1). The ISL3034E
and ISL3036E enter the SHDN mode when the EN input
switches low, or automatically when the VCC voltage drops
below the VL voltage. The ISL3035 has no enable pin, so it
enters SHDN only if VCC drops below VL. The VL supply
powers the EN circuitry.
ISL3034E and ISL3036E
The ISL3034E and ISL3036E are general purpose level
translators featuring an enable pin, and six or four channels,
9
FIGURE 6. ISL3035E IN AN SD CARD APPLICATION
The ISL3035E specifically targets memory card applications,
and Figure 6 illustrates its use in an SD Card application.
Instead of six general purpose channels, the ISL3035E
features five general purpose channels and one dedicated
CLK channel. In memory card applications, the CLK channel
is a unidirectional signal driven by the host controller and
used by the memory card to synchronize data reads and
writes. The ISL3035E’s CLK channel is unique in that the
host CLK applied to the CLK_VL pin routes to the memory
card via the CLK_VCC pin, but it also loops back to the host
on the CLK_RET pin. This CLK_RET signal better mimics
the timing of “read” data returned from the memory card (see
Figure 21 for signal timing), so using CLK_RET as the host’s
input CLK improves the CLK to data timing relationship.
CLK_RET is strictly an output, and CLK_VL is strictly an
input. If an ISL3035E application needs a sixth I/O channel
then the user needs to connect CLK_VL and CLK_RET
together. Connected this way, the combination channel has the
same architecture as the other I/O channels. Both CLK_RET
and CLK_VL have equivalent pull-up current sources and
SHDN pull-up resistors, so connecting these two pins together
doubles the pull-up current in either mode.
The bit-by-bit auto direction control eliminates the need for
GPIO signals to control the flow of data on the CMD and
DAT lines.
The ISL3035E has no enable pin, so it only enters the low
power SHDN mode when VCC drops below VL. There are no
SHDN pull-up resistors on the I/OVCC and CLK_VCC pins,
but there are 75kΩ pull-ups on the I/OVL, CLK_VL, and
CLK_RET pins.

Best-in-Class ESD Protection
All pins on these devices include class 3 (>12kV) Human
Body Model (HBM) ESD protection structures, but the input
and I/O pins incorporate advanced structures allowing
them to survive ESD events in excess of ±15kV HBM and
±15kV to IEC61000-4-2. The I/OVCC pins are particularly
vulnerable to ESD damage because they typically connect
to an exposed port on the exterior of the finished product.
Simply touching the port pins, or connecting a memory
card, can cause an ESD event that might destroy
unprotected ICs. These new ESD structures protect the
device whether or not it is powered up and without
degrading the level shifting performance. This built-in ESD
protection eliminates the need for board level protection
structures (e.g., transient suppression diodes) and the
associated, undesirable capacitive load they present. To
ensure the full benefit of the built-in ESD protection,
connect the IC’s GND pin directly to a low impedance GND
plane.
IEC61000-4-2 Testing
The IEC61000 test method applies to finished equipment,
rather than to an individual IC. Therefore, the pins most likely
to suffer an ESD event are those that are exposed to the
outside world (typically I/OVCC pins in memory card
applications) but the ISL3034E, ISL3035E, and ISL3036E
feature IEC61000 ESD protection on all logic and I/O pins
(both I/OVL and I/OVCC, as well as CLK pins). Unlike HBM
and MM methods which only test each pin-to-pin
combination without applying power, IEC61000 testing is
also performed with the IC in its typical application
Typical Performance Curves
configuration (power applied). The IEC61000 standard’s
lower current limiting resistor coupled with the larger charge
storage capacitor yields a test that is much more severe than
the HBM test. The extra ESD protection built into these
devices’ pins allows the design of equipment meeting level 4
criteria without the need for additional board level protection.
AIR-GAP DISCHARGE TEST METHOD
For this test method, a charged probe tip moves toward the
IC pin until the voltage arcs to it. The current waveform
delivered to the IC pin depends on approach speed,
humidity, temperature, etc., so it is difficult to obtain
repeatable results. All the EN, CLK, and I/O pins withstand
±15kV air-gap discharges, relative to GND.
CONTACT DISCHARGE TEST METHOD
During the contact discharge test, the probe contacts the
tested pin before the probe tip is energized, thereby
eliminating the variables associated with the air-gap
discharge. The result is a more repeatable and predictable
test, but equipment limits prevent testing devices at voltages
higher than ±9kV. Devices in this family survive ±9kV contact
discharges (relative to the GND pin) on the EN, CLK, and I/O
pins.
Layout and Decoupling Considerations
These level translators’ high data rates and fast signal
transitions require that the accelerators have high transient
currents. Thus, short, low inductance supply traces and
decoupling within 1/8th inch of the IC are imperative with
very low impedance GND return paths.
