74AC253, 74ACT253 Rev. 1.5

74AC253, 74ACT253

Dual 4-Input Multiplexer with 3-STATE Outputs

Features

General Description

The AC/ACT253 is a dual 4-input multiplexer with

3-STATE outputs. It can select two bits of data from four

sources using common 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.

Ordering Information

Device also available Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
