SN54/74LS153
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 (S0, S1). The two 4-input multi-
plexer circuits have individual active LOW Enables (Ea, Eb)
which can be used to strobe the outputs independently. When
the Enables (Ea, Eb) are HIGH, the corresponding outputs (Za,
Zb) are forced LOW.
The LS153 is the logic implementation of a 2-pole, 4-posi-
tion 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 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 a function genera-
tor. The LS153 can generate two functions of three variables.
This is useful for implementing highly irregular random logic.
