54ACT258
Quad 2-Input Multiplexer with TRI-STATE® Outputs
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 out-
puts 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
n ICC and IOZ reduced by 50%
n Multiplexer expansion by tying outputs together
n Inverting TRI-STATE outputs
n Outputs source/sink 24 mA
n ’ACT258 has TTL-compatible inputs
n Standard Military Drawing (SMD)
— ’ACT258: 5962-88704
— ’AC258: 5962-91604
