Overview
The 74AHC541PW is an 8-bit buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74AHC series and is designed to provide high performance and low power consumption. It features two output enables (OE1 and OE2), allowing the associated outputs to assume a high-impedance OFF-state when either OE is set to HIGH. The 74AHC541PW is suitable for use in mixed voltage environments due to its overvoltage tolerant inputs up to 5.5 V.
