54ACT253 Overview
The ’AC/’ACT253 is a dual 4-input multiplexer with TRI-STATE outputs. It can select two bits of data from four sources using mon select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems.
