Overview
The NLSV8T244DWR2G, 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 be configured from 0.9 V to 4.5 V. This flexibility allows for universal low-voltage translation from the input An to the output Bn port. The NLSV8T244 is particularly suited for applications requiring high-speed data transfer with balanced propagation delay and robust protection features.
