Overview
The 74VHC541PW,118 is an octal non-inverting buffer/line driver with 3-state bus compatible outputs, manufactured by Nexperia USA Inc. This high-speed Si-gate CMOS device is part of Nexperia’s extensive portfolio of logic ICs, designed to meet the demands of various electronic designs across multiple industries.
The device features two output enable inputs (OE0 and OE1) that control the 3-state outputs, allowing the outputs to assume a high-impedance OFF-state when the output enable is set to HIGH. This functionality makes it versatile for use in a wide range of applications, from automotive and industrial to consumer electronics.
