This dual Schmitt-trigger buffer is designed for 1.65-V to 5.5-V VCC operation. The SN74LVC2G17 contains two buffers and performs the Boolean function Y = A. The device functions as two independent buffers, 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.
