Dual 4-Input Multiplexer

The LSTTL / MSI SN74LS153 is a very high speed Dual 4-Input

Multiplexer with common select inputs and individual enable inputs

for each section. It can select two bits of data from four sources. The

two buffered outputs present data in the true (non-inverted) form. In

addition to multiplexer operation, the LS153 can generate any two

functions of three variables. The LS153 is fabricated with the Schottky

barrier diode process for high speed and is completely compatible with

all ON Semiconductor TTL families.

FUNCTIONAL DESCRIPTION

The LS153 is a Dual 4-input Multiplexer fabricated with

Low Power, Schottky barrier diode process for high speed.

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 multiplexer 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 LS153 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.

The LS153 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 a function

generator. The LS153 can generate two functions of three

variables. This is useful for implementing highly irregular

random logic.
