8 Detailed Description

8.1 Overview

The outputs of the SN74LS07 device are open-collector and can be connected to other open-collector outputs to

implement active-low wired-OR or active-high wired-AND functions. The maximum sink current for the SN74LS07

is 40 mA.

Inputs can be driven from 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.

Resistor values shown are nominal.
