Overview
The 74LVC2G14GW is a dual inverting Schmitt trigger with 5 V tolerant inputs, produced by NXP USA Inc. This device is part of the LVC (Low Voltage CMOS) family and is designed to operate in mixed 3.3 V and 5 V environments. It features Schmitt-trigger inputs, which provide high noise immunity, and standard push-pull outputs. The device is fully specified for partial power-down applications using IOFF circuitry, which disables the output to prevent damaging backflow current when the device is powered down.
