Overview
The TXB0104YZTR is a 4-bit bidirectional voltage-level translator produced by Texas Instruments. This device is designed to facilitate universal low-voltage bidirectional translation between different voltage nodes, making it versatile for various electronic systems. It uses two separate configurable power-supply rails, with the A port tracking VCCA (1.2 V to 3.6 V) and the B port tracking VCCB (1.65 V to 5.5 V). This allows for seamless communication between devices operating at different voltage levels.
