54F/74F153
Dual 4-Input Multiplexer
General Description
The ’F153 is a high-speed dual 4-input multiplexer with com-
mon select inputs and individual enable inputs for each sec-
tion. 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 ’F153 can
generate any two functions of three variables.
Features
YGuaranteed 4000V minimum ESD protection

Functional Description
The ’F153 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,S
1
). The two 4-input multiplexer
circuits have individual active LOW Enables (Ea,E
b
) which
can be used to strobe the outputs independently. When the
Enables (Ea,E
b
) are HIGH, the corresponding outputs (Za,
Zb) are forced LOW. The ’F153 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 as
follows:
ZaeEa#(I0a#S1#S0aI1a#S1#S0a
I2a#S1#S0aI3a#S1#S0)
ZbeEb#(I0b#S1#S0aI1b#S1#S0a
I2b#S1#S0aI3b#S1#S0)
The ’F153 can be used to move data from a group of regis-
ters to a common output bus. The particular register from
which the data came would be determined by the state of
the Select inputs. A less obvious application is as a function
generator. The ’F153 can generate two functions of three
variables. This is useful for implementing highly irregular
random logic.
