Dual 4-Input Multiplexer
General Description
Features
The ’AC/’ACT153 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
’AC/’ACT153 can act as a function generator and generate
any two functions of three variables.

Functional Description
The ’AC/’ACT153 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 indepedently. When
the Enables (Ea, Eb) are HIGH, the corresponding outputs
Za, Zb) are forced LOW. The ’AC/’ACT153 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
Select inputs. The logic equations for the outputs are shown
below.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recommend operation of FACT ® circuits outside databook specifications.
