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 multiplexer 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-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 = Ea (I0a S1 S0 + I1a S1 S0 + I2a S1 S0 +
I3a S1 S0)
Zb = Eb (I0b S1 S0 + I1b S1 S0 + I2b S1 S0 +
I3b S1 S0)
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.
