Overview
The 74HCT244D-Q100,118 is an octal buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the 74HCT series and is designed to operate with TTL (Transistor-Transistor Logic) input levels. The device can be used as two 4-bit buffers or one 8-bit buffer, making it versatile for various digital circuit applications. It features two output enables (1OE and 2OE), each controlling four of the 3-state outputs, allowing for high-impedance OFF-state when the output enable is set to HIGH.
