3 Description

The SN74AC3G99 device contains three independent

configurable logic gates with 3-state outputs. Each

gate has four inputs and performs the boolean

function Y = (A•C+B•C)⊕D. All inputs include Schmitttriggers,

eliminating any erroneous data outputs due

to slow-edged or noisy input signals.
