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

FUNCTIONAL DESCRIPTION
The MC74AC153/74ACT153 is a dual 4-input multiplexer.
It can select two bits of data from up to four sources under the
control of the common Select inputs (S0, S1). The two 4-input
multiplexer circuits have individual active-LOW Enables
(Ea,Eb) which can be used to strobe the outputs
independently. When the Enables (Ea, Eb) are HIGH, the
corresponding outputs (Za, Zb) are forced LOW. The
MC74AC153/74ACT153 is the logic implementation of a
2-pole, 4-position switch, where the position of the switch is
determined by the logic levels supplied to the two Select
inputs. The logic equations for the outputs are shown below.
Za = Ea(I0aS1S0+I1aS1S0+I2aS1S0+I3aS1S0)
Zb = Eb(I0bS1S0+I1bS1S0+I2bS1S0+I3bS1S0)
