Overview
The 74AHC244PW,118 is an 8-bit buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This 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. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state, which is useful in mixed voltage environments due to its overvoltage tolerant inputs.
