Overview
The 74AHCT541PW,118 is an octal buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This high-speed Si-gate CMOS device is designed to provide balanced propagation delays and high noise immunity, making it suitable for a wide range of applications. The device features two output enables (OE1 and OE2), allowing the outputs to assume a high-impedance OFF-state when either enable is set to HIGH. It operates with TTL input levels and is overvoltage tolerant, accepting input voltages higher than VCC up to 5.5 V.
