The ’F153 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)
December 1994
form. In addition to multiplexer operation, the ’F153 can
generate any two functions of three variables.

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 (S

Enables (E

) are forced LOW. The ’F153 is the logic implementation

of a 2-pole, 4-position switch, where the position of the

The ’F153 can be used to move data from a group of registers 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.
