Overview
The 74LVC244AD-Q100J, produced by Nexperia USA Inc., is an octal non-inverting buffer/line driver with 3-state outputs. This device is part of the 74LVC and 74LVCH series, designed to operate in a wide range of supply voltages from 1.2 V to 3.6 V. It features two output enables (1OE and 2OE), each controlling four of the 3-state outputs, allowing for flexible use as two 4-bit buffers or one 8-bit buffer. The device is particularly useful in mixed 3.3 V and 5 V environments due to its ability to interface with both voltage levels.
