MC74ACT153
Dual 4ĆInput Multiplexer
The MC74AC153/74ACT153 is a high-speed dual 4-input multiplexer with
common select inputs and individual enable inputs for each section. It can select
two lines of data from four sources. The two buffered outputs present data in the
true (non-inverted) form. In addition to multiplexer operation, the MC74AC153/
74ACT153 can act as a function generator and generate any two functions of
three variables.
• Outputs Source/Sink 24 mA
• ′ACT153 Has TTL Compatible Inputs
