Overview
The NLSV2T244DMR2G is a 2-bit configurable dual-supply voltage level translator produced by onsemi. This device is designed to translate voltage levels between two different power supply rails, VCCA and VCCB, which can be configured from 0.9 V to 4.5 V. This universal low-voltage translation capability makes it versatile for various applications. The device features high-speed operation with balanced propagation delay and includes overvoltage tolerance (OVT) protection for inputs and outputs up to 4.5 V.
