The SN74LVC2G14DCKR is a Dual Schmitt-trigger Inverter, designed for 1.65 to 5.5V VCC operation. The SN74LVC2G14DCKR device contains two inverters and performs the Boolean function Y = A. The device functions as two independent inverters, but because of Schmitt action, it may have different input threshold levels for positive-going (VT+) and negative-going (VT-) signals. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

The 74LVC2G14GW is a dual Inverting Schmitt-trigger with 5V tolerant input. It is capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. The inputs can be driven from either 3.3V or 5V devices. This feature allows the use of this device in a mixed 3.3V and 5V environment. Schmitt-trigger action at the inputs makes the circuit tolerant of slower input rise and fall time. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
