Overview
The 74LVC126APW,112 is a quad buffer/line driver integrated circuit produced by Nexperia USA Inc. This device is designed with 3-state outputs controlled by the output enable inputs (nOE), allowing the outputs to assume a high impedance OFF-state when nOE is LOW. It is particularly useful in mixed 3.3 V and 5 V environments due to its 5 V tolerant input/outputs.
The 74LVC126A series, including the 74LVC126APW,112, features Schmitt-trigger action at all inputs, making the circuit tolerant of slower input rise and fall times. It is fully specified for partial power down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
