74AHCV05APW集成電路（IC）的門反相器規(guī)格書PDF中文資料

1. General description

The 74AHCV05A is a hex inverter with Schmitt trigger inputs and open-drain outputs. The outputs

are open-drain and can be connected to other open-drain outputs to implement active-LOW wired-

OR or active-HIGH wired-AND functions.

Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed

voltage environments.

The data (nA) inputs include Schmitt trigger inputs capable of transforming slowly changing input

signals into sharply defined, jitter-free output signals.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.
