8 Detailed Description

8.1 Overview

The SN74AUP1T17 device contains one Schmitt trigger buffer and performs the Boolean function Y = A. 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.

8.2 Functional Block Diagram

8.3 Feature Description

The distinguishing feature of the SN74AUP1T17 versus its standard-logic counterpart, the SN74AUP1G17, is the

lowered switching input threshold. The SN74AUP1T17 will switch to a high output at a lower voltage threshold,

which allows up-translation from signals that may not reach VCC levels.

The IOFF feature prevents the outputs from sinking current when VCC = 0 V, providing extra isolation in systems

where not all modules are powered simultaneously.
