FAIRCHILD FXLA0104QFX

FXLA0104
Low-Voltage Dual-Supply 4-Bit Voltage Translator with
Configurable Voltage Supplies and Signal Levels,
3-State Outputs, and Auto Direction Sensing
Features
Description

Bi-Directional Interface between Two Levels:
from 1.1V to 3.6V


Fully Configurable: Inputs and Outputs Track VCC



Outputs Switch to 3-State if Either VCC is at GND
The FXLA0104 is a configurable dual-voltage supply
translator for both uni-directional and bi-directional
voltage translation between two logic levels. The device
allows translation between voltages as high as 3.6V to
as low as 1.1V. The A port tracks the VCCA level and the
B port tracks the VCCB level. This allows for bi-directional
voltage translation over a variety of voltage levels: 1.2V,
1.5V, 1.8V, 2.5V, and 3.3V.


Control Input (OE) Referenced to VCCA Voltage


Direction Control Not Necessary

ESD Protection Exceeds:
- 6kV HBM (per JESD22-A114 & Mil Std 883e
3015.7)
- 2kV CDM (per ESD STM 5.3)
Non-Preferential Power-Up; Either VCC May Be
Powered Up First
Power-Off Protection
Bus-Hold on Data Inputs Eliminates the Need for
Pull-Up Resistors; Do Not Use Pull-Up Resistors on
A or B Ports
Available in the 12-Lead, 1.7mm x 2.0mm UMLP
Package
100Mbps Throughput when Translating Between
1.8V and 2.5V
The device remains in three-state as long as either
VCC=0V, allowing either VCC to be powered up first.
Internal power-down control circuits place the device in
3-state if either VCC is removed.
The OE input, when LOW, disables both the A and B
ports by placing them in a 3-state condition. The OE
input is supplied by VCCA.
The FXLA0104 supports bi-directional translation
without the need for a direction control pin. The two
ports of the device have auto-direction sense capability.
Either port may sense an input signal and transfer it as
an output signal to the other port.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

FXL translators offer an advantage in that either VCC
may be powered up first. This benefit derives from the
chip design. When either VCC is at 0V, outputs are in a
high-impedance state. The control input (OE) is
designed to track the VCCA supply.
The recommended power-down sequence is:
The recommended power-up sequence is:
Pull-Up/Pull-Down Resistors

2.
3.
1.
2.
3.
Do not use pull-up or pull-down resistors. This device
has bus-hold circuits: pull-up or pull-down resistors are
not recommended because they interfere with the
output state. The current through these resistors may
exceed the hold drive, II(HOLD) and/or II(OD) bus-hold
currents, resulting in data transition and/or autodirection sensing failures. The bus-hold feature
eliminates the need for extra resistors.
Apply power to the first VCC.
Apply power to the second VCC.
Drive the OE input HIGH to enable the device.

Remove power from either VCC.
Remove power from other VCC.

13. Maximum data rate is guaranteed, but not tested.
14. Maximum data rate is specified in megabits per second (see Figure 9). It is equivalent to two times the
F-toggle frequency, specified in megahertz. For example, 100Mbps is equivalent to 50MHz.

hold.” “Static Mode” is when only the bus hold drives the
channel. The bus hold can be over ridden in the event of
a direction change. The strong driver allows the
FXLA0104 to quickly charge and discharge capacitive
transmission lines during dynamic mode. Static mode
conserves power, where ICC is typically < 5µA.
The FXLA0104 I/O architecture benefits the end user,
beyond level translation, in the following three ways:
Auto Direction without an external direction pin.
Drive Capacitive Loads. Automatically shifts to a
higher current drive mode only during “Dynamic Mode”
or HL / LH transitions.
Bus Hold Minimum Drive Current
Lower Power Consumption. Automatically shifts to
low-power mode during “Static Mode” (no transitions),
lowering power consumption.
Specifies the minimum amount of current the bus hold
driver can source/sink. The bus hold minimum drive
current (IIHOLD) is VCC dependent and guaranteed in the
DC Electrical tables. The intent is to maintain a valid
output state in a static mode, but that can be overridden
when an input data transition occurs.
The FXLA0104 does not require a direction pin. Instead,
the I/O architecture detects input transitions on both
side and automatically transfers the data to the
corresponding output. For example, for a given channel,
if both A and B side are at a static LOW, the direction
has been established as A  B, and a LH transition
occurs on the B port; the FXLA0104 internal I/O
architecture automatically changes direction from A  B
to B  A.
Bus Hold Input Overdrive Drive Current
Specifies the minimum amount of current required (by
an external device) to overdrive the bus hold in the
event of a direction change. The bus hold overdrive
(IIODH, IIODL) is VCC dependent and guaranteed in the DC
Electrical tables.
During HL / LH transitions, or “Dynamic Mode,” a strong
output driver drives the output channel in parallel with a
weak output driver. After a typical delay of
approximately 10ns – 50ns, the strong driver is turned
off, leaving the weak driver enabled for holding the logic
state of the channel. This weak driver is called the “bus
