DESCRIPTION/ORDERING INFORMATION
The TCA9406 is a dual bidirectional I2C-Bus and SMBus Voltage-Level translator with enable (OE) Input. It is
operational from 1.65 V to 3.6 V on A-Port and 2.3 V to 5.5 V on B-port. Enable (OE) input is referenced to
VCCA with a maximum input voltage tolerance of 4.6 V.
The TCA9406 can operate up to 24Mbps in push pull mode and 2Mbps with open drain mod. Its compatible
with a standard I2C bus 100 kHz, 400 kHz and 1 MHz at both sides of A-Port and B-Port.

With the standard I2C bus system, it needs pull-up resistors to provide logic HIGH levels on the translator
bus. The TCA9406 is an open-drain bus level configuration of the I2C-bus. The value of pullup resistors
depends on the system, but each side of the translator must have pull-up resistors and TCA9406 already has
10 kΩ pullup resistors on each side and it allows to add additional external pull-up resistors. It can work with
standard-mode, fast-mode and fast mode plus I2C-bus devices in additional to SMBus.
The TCA9406 is not a bus buffer like the PCA9515A and PCA9517. It provides both level translation and
physically isolates the capacitance to either side of the bus when both sides are connected. The Ioff feature
can be utilized to isolate the bus into high impedance when using the power supply to off the either VCCA or
VCCB
.
The Enable (OE) should be tied to GND through a pulldown resistor to ensure the high-impedance state
during power up or power down. The minimum value of the resistor is determined by the current-sourcing
capability of the driver.

PRINCIPLES OF OPERATION
Application Notes
The TCA9406 A-Port I/O has open-drain outputs with an internal 10-kΩ pullup resistor to VCCA, and B-Port I/O
has an internal 10-kΩ pullup resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor
must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-kΩ resistors). Adding lower value
pullup resistors changes VOL levels. When the OE pin is set low, the internal pullups of the TCA9406 are
disabled for power saving caused by pullup resistors.
Figure 1. Typical Design Example
The TCA6406 has a VCC isolation feature known as Ioff partial power down and backdrive protection. If a cable is
connected, and the connected external system is still powered own, the system can be put into standby mode by
shutting down the power rail. In this state, the TCA6406 has a leakage current of approximately 2 µA caused by
current flow from powered-on system.
Power Up, Power Down
One advantage of the TCA9406 translator is that either power supply can be ramped up first. Another advantage
is that either power supply can be set to 0 V, and the outputs are in high-impedance state.
The recommended power up sequence is:
1. Apply power to the first VCC and apply the second VCC
2. Drive the OE input high to enable the device
The recommended power down sequence is:
1. Drive OE input low to disable the device
2. Switch Off the power from either VCC and remove power from other VCC
.
Enable/Disable
The TCA9406 han an OE input that is used to disable the device by setting OE low, which place all I/Os in the
high-impedance state. The control OE is referenced to the VCCA supply. A pulldown resistor tying OE to ground
should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power up
and power down. The value of resistor is based upon the current sinking capability of the device.

Integrated Pullup Resistors on the I/Os (A-Ports/B-Ports)
Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup
resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O
to VCCA or VCCB (in parallel with the internal 10-kΩ resistors). Adding lower value pull-up resistors may effect VOL
levels, however. The internal pullups of the PCA9406 are disabled when the OE pin is low.
