TITXB0108QPWRQ1
Overview
The TXB0108QPWRQ1 is an automotive-qualified (AEC-Q100) 8-bit bidirectional voltage-level translator featuring auto-direction sensing. It enables seamless data communication between devices operating on different logic supply rails, ranging from 1.2V to 3.6V on Port A and 1.65V to 5.5V on Port B. This part is specifically designed for push-pull CMOS logic interfaces and includes VCC isolation to ensure high-impedance states during power-down.
Why Choose This Part
The auto-direction sensing capability eliminates the need for a DIR control signal, simplifying PCB routing and reducing MCU pin count. It features integrated 15kV ESD protection and Ioff circuitry for partial-power-down mode, preventing damaging backflow current when a subsystem is powered off.
Applications
Getting Started
Ensure that the VccA supply voltage is always less than or equal to VccB for proper operation. Decouple both supply pins with 0.1uF capacitors placed close to the TSSOP-20 package. For evaluation, use a TSSOP-20 breakout board or the TXB0108EVM evaluation module to verify signal integrity with your specific capacitive load.
