7 Detailed Description

7.1 Overview

The SN74AC596 device contains three independent ultra-configurable gates with 3-state outputs. Each gate

has an independent active-low output enable (OE). Each channel of the device performs the boolean function

Y = (A•C+B•C)

⊕D. The user can choose logic functions, such as MUX, AND, OR, NAND, NOR, XOR, XNOR,

inverter, and buffer by connecting the inputs A, B, C, and D appropriately.
