Features
■ ICC and IOZ reduced by 50%
■ Multiplexer expansion by tying outputs together
■ Inverting 3-STATE outputs
■ Outputs source/sink 24mA
■ TTL-compatible inputs
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 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.
