Overview
The TXS0104ERGYR is a 4-bit bidirectional voltage-level translator produced by Texas Instruments. This component is designed for open-drain and push-pull applications, allowing for low-voltage bidirectional translation between various voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5 V. It features two separate configurable power-supply rails, with the A port tracking VCCA (1.65 V to 3.6 V) and the B port tracking VCCB (2.3 V to 5.5 V). The device does not require a direction-control signal and ensures that all outputs are in a high-impedance state when the output-enable (OE) input is low.
