Overview
The TXS0101DBVR is a 1-bit bidirectional voltage-level translator produced by Texas Instruments. This component is designed to facilitate voltage translation between different voltage nodes, making it a versatile tool in various electronic systems. The device operates with two separate configurable power-supply rails, allowing it to translate signals between voltage levels ranging from 1.65V to 3.6V on the A port and 2.3V to 5.5V on the B port. This feature enables seamless communication between different voltage domains in a system, such as 1.8V, 2.5V, 3.3V, and 5V nodes.
