Overview
The 74LVC244APW,112 is an 8-bit buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74LVC244A and 74LVCH244A series, which are designed to operate in a wide range of supply voltages from 1.2 V to 3.6 V. It can be used as two 4-bit buffers or one 8-bit buffer, making it versatile for various digital logic applications. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs, allowing for flexible control over the output states.
