74ACT258
Quad 2-Input Multiplexer with 3-STATE Outputs
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-ori-
ented systems.
Features
s ICC and IOZ reduced by 50%
s Multiplexer expansion by tying outputs together
s Inverting 3-STATE outputs
s Outputs source/sink 24 mA
s TTL-compatible inputs
