PCA9306
Dual bidirectional I2C-bus and SMBus voltage-level translator
Rev. 05 — 19 March 2010
Product data sheet
1. General description
The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an
enable (EN) input, and is operational from 1.0 V to 3.6 V (Vref(1)) and 1.8 V to 5.5 V
(Vbias(ref)(2)).
The PCA9306 allows bidirectional voltage translations between 1.0 V and 5 V without the
use of a direction pin. The low ON-state resistance (Ron) of the switch allows connections
to be made with minimal propagation delay. When EN is HIGH, the translator switch is on,
and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively,
allowing bidirectional data flow between ports. When EN is LOW, the translator switch is
off, and a high-impedance state exists between ports.
The PCA9306 is not a bus buffer like the PCA9509 or PCA9517A that provide both level
translation and physically isolates the capacitance to either side of the bus when both
sides are connected. The PCA9306 only isolates both sides when the device is disabled
and provides voltage level translation when active.
The PCA9306 can also be used to run two buses, one at 400 kHz operating frequency
and the other at 100 kHz operating frequency. If the two buses are operating at different
frequencies, the 100 kHz bus must be isolated when the 400 kHz operation of the other
bus is required. If the master is running at 400 kHz, the maximum system operating
frequency may be less than 400 kHz because of the delays added by the translator.
As with the standard I2C-bus system, pull-up resistors are required to provide the logic
HIGH levels on the translator’s bus. The PCA9306 has a standard open-collector
configuration of the I2C-bus. The size of these pull-up resistors depends on the system,
but each side of the translator must have a pull-up resistor. The device is designed to work
with Standard-mode, Fast-mode and Fast mode Plus I2C-bus devices in addition to
SMBus devices. The maximum frequency is dependent on the RC time constant, but
generally supports > 2 MHz.
When the SDA1 or SDA2 port is LOW, the clamp is in the ON-state and a low resistance
connection exists between the SDA1 and SDA2 ports. Assuming the higher voltage is on
the SDA2 port when the SDA2 port is HIGH, the voltage on the SDA1 port is limited to the
voltage set by VREF1. When the SDA1 port is HIGH, the SDA2 port is pulled to the drain
pull-up supply voltage (Vpu(D)) by the pull-up resistors. This functionality allows a
seamless translation between higher and lower voltages selected by the user without the
need for directional control. The SCL1/SCL2 channel also functions as the SDA1/SDA2
channel.

NXP Semiconductors
Dual bidirectional I2C-bus and SMBus voltage-level translator
All channels have the same electrical characteristics and there is minimal deviation from
one output to another in voltage or propagation delay. This is a benefit over discrete
transistor voltage translation solutions, since the fabrication of the switch is symmetrical.
The translator provides excellent ESD protection to lower voltage devices, and at the
same time protects less ESD-resistant devices.

NXP Semiconductors
Dual bidirectional I2C-bus and SMBus voltage-level translator
11.1 Bidirectional translation
For the bidirectional clamping configuration (higher voltage to lower voltage or lower
voltage to higher voltage), the EN input must be connected to VREF2 and both pins pulled
to HIGH side Vpu(D) through a pull-up resistor (typically 200 kΩ). This allows VREF2 to
regulate the EN input. A filter capacitor on VREF2 is recommended. The I2C-bus master
output can be totem-pole or open-drain (pull-up resistors may be required) and the
I2C-bus device output can be totem-pole or open-drain (pull-up resistors are required to
pull the SCL2 and SDA2 outputs to Vpu(D)). However, if either output is totem-pole, data
must be unidirectional or the outputs must be 3-stateable and be controlled by some
direction-control mechanism to prevent HIGH-to-LOW contentions in either direction. If
both outputs are open-drain, no direction control is needed.
The reference supply voltage (Vref(1)) is connected to the processor core power supply
voltage. When VREF2 is connected through a 200 kΩ resistor to a 3.3 V to 5.5 V Vpu(D)
power supply, and Vref(1) is set between 1.0 V and (Vpu(D) − 1 V), the output of each SCL1
and SDA1 has a maximum output voltage equal to VREF1, and the output of each SCL2
and SDA2 has a maximum output voltage equal to Vpu(D).

11.2 Sizing pull-up resistor
The pull-up resistor value needs to limit the current through the pass transistor when it is
in the ON state to about 15 mA. This ensures a pass voltage of 260 mV to 350 mV. If the
current through the pass transistor is higher than 15 mA, the pass voltage also is higher in
the ON state. To set the current through each pass transistor at 15 mA, the pull-up resistor
value is calculated as:
V pu ( D ) – 0.35 V
R PU = ------------------------------------0.015 A
(1)
Table 10 summarizes resistor reference voltages and currents at 15 mA, 10 mA, and
3 mA. The resistor values shown in the +10 % column or a larger value should be used to
ensure that the pass voltage of the transistor would be 350 mV or less. The external driver
must be able to sink the total current from the resistors on both sides of the PCA9306
device at 0.175 V, although the 15 mA only applies to current flowing through the
PCA9306 device.

11.2.1 Maximum frequency calculation
The maximum frequency is totally dependent upon the specifics of the application and the
device can operate > 33 MHz. Basically, the PCA9306 behaves like a wire with the
additional characteristics of transistor device physics and should be capable of performing
at higher frequencies if used correctly.
Here are some guidelines to follow that will help maximize the performance of the device:
• Keep trace length to a minimum by placing the PCA9306 close to the processor.
• The trace length should be less than half the time of flight to reduce ringing and
reflections.
• The faster the edge of the signal, the higher the chance for ringing.
• The higher the drive strength (up to 15 mA), the higher the frequency the device can
use.
In a 3.3 V to 1.8 V direction level shift, if the 3.3 V side is being driven by a totem pole type
driver no pull-up resistor is needed on the 3.3 V side. The capacitance and line length of
concern is on the 1.8 V side since it is driven through the ON resistance of the PCA9306.
If the line length on the 1.8 V side is long enough there can be a reflection at the
chip/terminating end of the wire when the transition time is shorter than the time of flight of
the wire because the PCA9306 looks like a high-impedance compared to the wire. If the
wire is not too long and the lumped capacitance is not excessive the signal will only be
slightly degraded by the series resistance added by passing through the PCA9306. If the
lumped capacitance is large the rise time will deteriorate, the fall time is much less
affected and if the rise time is slowed down too much the duty cycle of the clock will be
degraded and at some point the clock will no longer be useful. So the principle design
consideration is to minimize the wire length and the capacitance on the 1.8 V side for the
clock path. A pull-up resistor on the 1.8 V side can also be used to trade a slower fall time
for a faster rise time and can also reduce the overshoot in some cases.

11.2.1.1
Example maximum frequency
Question — We need to make the PLL area of a new line card backwards compatible and
need to need to convert one GTL signal to LVTTL, invert it, and convert it back to GTL.
The signal we want to convert is random in nature but will mostly be around 19 MHz with
very long periods of inactivity where either a HIGH or LOW state will be maintained. The
traces are 1 or 2 inches long with trace capacitance of about 2 pF per inch.
Answer — The frequency of the PCA9306 is limited by the capacitance of the part, the
capacitance of the traces and the pull-up resistors used. The limiting case is probably the
LOW-to-HIGH transition in the GTL to LVTTL direction, and there the use of the lowest
acceptable resistor values will minimize the rise time delay. Assuming 50 pF capacitance
and 220 Ω resistance, the RC time constant is 11 ns (50 pF × 220 Ω). With 19 MHz
corresponding to 50 ns period the PCA9306 will support this application.

13. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
13.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
13.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering
13.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

13.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 20) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 11 and 12
