Description

Description: This is a breakout board for the Texas Instruments TXB0104 module. The TXB0104 is a 4-bit bidirectional voltage-level translator with automatic direction sensing.

This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB. We have broken out each pin on this module for you to easily access both the A and B ports.

Features:

1.2V to 3.6V on A Port and 1.65V to 5.5V on B Port (VCCA ≤ VCCB) VCC Isolation Feature – If Either VCC Input Is at GND, All Outputs Are in the High-Impedance State OE Input Circuit Referenced to VCC Low Power Consumption, 5-μA Max ICC
