DESCRIPTION/ORDERING INFORMATION
This hex Schmitt-trigger buffer is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.65-V to
1.95-V VCC operation.
The SN74AUC17 contains six independent buffers and performs the Boolean function Y = A. The device
functions as six 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.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
(3) The package thermal impedance is calculated in accordance with JESD 51-5.
