Overview
The NLSV4T244DTR2G is a 4-bit configurable dual-supply voltage level translator produced by onsemi. This component is designed to facilitate voltage translation between two different power supply rails, VCCA and VCCB, which can operate within a wide range of 0.9 V to 4.5 V. This versatility makes it suitable for various low-voltage translation applications. The device features high-speed operation with balanced propagation delay and includes overvoltage tolerance (OVT) protection up to 4.5 V for both inputs and outputs.
