TXB0104ZXUR

Translators, Level Shifters Overview

The TXB0104ZXUR is a 4-bit bidirectional voltage-level translator from the Texas Instruments TXB0104 series. It utilizes two separate configurable power-supply rails to facilitate universal low-voltage translation between various logic nodes, including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V. The A port accepts supply voltages from 1.2V to 3.6V, while the B port supports 1.65V to 5.5V, with the constraint that VCCA must not exceed VCCB. This non-inverting translator features auto direction sensing and includes Ioff circuitry to prevent damaging current backflow during power-down states.

Translators, Level Shifters Feature Summary

• Supports universal bidirectional translation across multiple standard voltage nodes
