FAST AND LS TTL DATA

DUAL 4-INPUT MULTIPLEXER

The MC54/74F153 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 F153 can
generate any two functions of three variables.

FUNCTIONAL DESCRIPTION

The MC54/74F153 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 independently. When
the Enables (E

a

, Eb) 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 shown below:

Za = E

a

• (I0a • S1 • S0 + I1a • S1 • S0 +

I2a • S1 • S

0

+ I3a • S1 • S0)

Zb = E

b

• (I0b • S1 • S0 + I1b • S1 • S0 +

I2b • S1 • S

0

+ I3b • S1 • S0)

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.
