Dual 4-Input Multiplexer with 3-STATE Outputs

Features

General Description

■ I and I reduced by 50%

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.

■ Multifunction capability

■ Non inverting 3-STATE outputs

■ Outputs source/sink 24mA

■ ACT253 has TTL-compatible inputs
