Dual 4-Input Multiplexer
General Description
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 gener-
ate 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 (S
0
, S
1
). The two 4-input multi-
plexer circuits have individual active-LOW Enables (E
a
, E
b
)
which can be used to strobe the outputs independently.
When the Enables (E
a
, E
b
) are HIGH, the corresponding
outputs Z
a
, Z
b
) 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, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACT circuits outside databook specifications.
