9 Detailed Description

9.1 Overview

This quadruple 2-input positive-OR gate is designed for 2-V to 5.5-V VCC operation.

The SN74LV32A device performs the Boolean function bf_cas286.gif in positive logic.

This part has low drive which produces slower rise and fall times that will reduce ringing on the output signal. The inputs and outputs are of high impedance when VCC = 0 V.
