54F/74F158A Quad 2-Input Multiplexer

November 1994

General Description

The ’F158A is a high speed quad 2-input multiplexer. It se­lects four bits of data from two sources using the common
Select and Enable inputs. The four outputs present the se­lected data in the inverted form. The ’F158A can also gener­ate any four of the 16 different functions of two variables.

Functional Description

The ’F158A quad 2-input multiplexer selects four bits of
data from two sources under the control of a common Se­lect input (S) and presents the data in inverted form at the
four outputs. The Enable input (E
HIGH, all of the outputs (Z

) is active LOW. When E is

) are forced HIGH regardless of
all other inputs. The ’F158A is the logic implementation of a
4-pole, 2-position switch where the position of the switch is
determined by the logic levels supplied to the Select input.

A common use of the ’F158A is the moving of data from two
groups of registers to four common output busses. The par­ticular register from which the data comes is determined by
the state of the Select input. A less obvious use is as a
function generator. The ’F158A can generate four functions
of two variables with one variable common. This is useful for
implementing gating functions.
