74F253 Overview
The 74F253 is a dual 4-input multiplexer with 3-STATE outputs. It can select two bits of data from four sources using mon select inputs. The output 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.
