General Description
The ’AC/’ACT258 is a quad 2-input multiplexer with TRI-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 TRI-STATE outputs
■ Outputs source/sink 24 mA
■ ’ACT258 has TTL-compatible inputs
■ Standard Military Drawing (SMD)
