General Description

The ACT258 is a quad 2-input multiplexer with 3-STATE outputs. Four bits of data from two sources can be selected using a common data select input. The four outputs present the selected data in the complement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.

Features

■ ICC and IOZ reduced by 50

■ Multiplexer expansion by tying outputs together

■ Inverting 3-STATE outputs

■ Outputs source/sink 24 mA

■ TTL-compatible inputs
