Overview
The NLSV4T3144MUTAG, produced by onsemi, is a 4-bit configurable dual-supply bus buffer level translator. This device is designed to translate voltage levels between two different power supply rails, VCCA and VCCB, which can operate within a range of 1.6 V to 3.6 V. It is particularly useful in applications requiring low-voltage translation and high-speed data transfer with balanced propagation delays.
