3 Description

The SN74AC3G99-Q1 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 Schmitt-triggers, eliminating any erroneous

data outputs due to slow-edged or noisy input signals.
