2-Bit Bidirectional Voltage-Level Shifter for Open-Drain and Push-Pull Application

Inquiry Add To Bom

TXS0102DCTT General Description

The TXS0102DCTT is a bidirectional voltage level translator designed to translate signals between two voltage domains. It is commonly used to interface between low-voltage systems, such as those operating at 1.2V, 1.5V, or 1.8V, and higher-voltage systems, such as those operating at 2.5V, 3.3V, or 5V.
