Product Overview
The TXS0104EZXUR is a 4-bit bidirectional voltage-level translator from Texas Instruments, designed for open-drain and push-pull applications. This directionless translator uses two separate configurable power-supply rails, allowing low-voltage bidirectional translation between 1.8V, 2.5V, 3.3V, and 5V voltage nodes. Packaged in a 12-ball DSBGA (ZXU) package, it provides ESD protection up to 15kV on the B port and requires no direction-control signal.
