8 Detailed Description

8.1 Overview

The outputs of the SN74LVC07A device are open drain and can be connected to other open-drain outputs to

implement active-low wired-OR or active-high wired-AND functions. The maximum sink current is 24 mA.

Inputs can be driven from 1.8-V, 2.5-V, 3.3-V (LVTTL), or 5-V (CMOS) devices. This feature allows the use of

this device as translators in a mixed-system environment.

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.
