TITXB0102YZPR
Overview
The TXB0102YZPR is a 2-channel, bidirectional voltage-level translator featuring auto-direction sensing, eliminating the need for a direction-control signal. It supports translation between 1.2 V and 3.6 V on Port A and 1.65 V and 5.5 V on Port B, making it ideal for interfacing low-voltage microcontrollers with higher-voltage peripherals. The device is designed in an ultra-small 8-DSBGA package, measuring approximately 0.9 mm by 1.8 mm.
Why Choose This Part
The TXB series is highly versatile because it automatically detects signal direction, significantly reducing PCB trace count and MCU pin requirements. It features Vcc isolation, ensuring that if either Vcc input is at ground, all outputs enter a high-impedance state. With a low standby current of 4 uA and 100 Mbps data rate capability, it balances high performance with power efficiency.
Applications
Key Specifications
Getting Started
To use this part, ensure VCCA is always less than or equal to VCCB and both supplies are properly bypassed with 0.1 uF capacitors. Because it uses a weak buffer architecture for auto-sensing, avoid using external pull-up resistors smaller than 50k ohms which can interfere with the translator logic. Prototyping is best handled using a DSBGA-to-DIP adapter or a dedicated breakout board due to the 0.4 mm ball pitch.
