Overview
The NLSV8T244DTR2G, produced by onsemi, is an 8-bit configurable dual-supply voltage level translator. This device is designed to translate voltage levels 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 flexibility makes it suitable for various low-voltage translation applications. The NLSV8T244DTR2G features high-speed operation with balanced propagation delay and includes overvoltage tolerance (OVT) protection up to 4.5 V for both inputs and outputs.
