Buffer, 74LVC1G17, 1.65V to 5.5V, SOT-23-5 - 

The SN74LVC1G17DBVT is a single Schmitt-trigger Buffer designed for 1.65 to 5.5V VCC operation. This device contains one buffer and performs the Boolean function Y = A. The CMOS device has high output drive while maintaining low static power dissipation over a broad VCC operating range. The device functions as an independent buffer, but because of Schmitt action, it will have different input threshold levels for a positive-going (VT+) and negative-going 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.
