9.1 Overview

The outputs of the SN74LV07A 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 16 mA at
5-V V_CC. Inputs can be driven from 2.5-V, 3.3-V, or 5-V (CMOS) devices. This feature allows the use of the SN74LV07A device as a translator in a mixed-system environment. This device is fully specified for partial power-down applications using I_off. The I_off circuitry disables the outputs, thus preventing a damaging current backflow through the device when it is powered down.

9.3 Feature Description

• Wide operating voltage range
  • Operates from 2 V to 5.5 V
• Allows up or down voltage translation
  • Inputs and outputs accept voltages to 5.5 V
• I_off feature
  • Allows voltages on the inputs and outputs when V_CC is 0 V
