93L09
Dual 4-Input Multiplexer
General Description
Features
The 93L09 monolithic dual 4-input digital multiplexers consist of two multiplexing circuits with common input select
logic. Each circuit contains four inputs and fully buffered
complementary outputs. In addition to multiplexer operation,
the 93L09 can generate any two functions of three variables. Active pullups in the outputs ensure high drive and
high speed performance. Because of its high speed performance and on-chip select decoding, the 93L09 may be
cascaded to multiple levels so that any number of lines can
be multiplexed onto a single output bus.

Absolute Maximum Ratings
(Note)
Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.

Functional Description
Truth Table
The 93L09 dual 4-input multiplexers are able to select two
bits of either HIGH or LOW data or control from up to four
sources, in one package. The 93L09 is the logical implementation of two-pole, four-position switch, with the position
of the switch being set by the logic levels supplied to the
two select inputs. Both assertion and negation outputs are
provided for both multiplexers. The logic equations for the
outputs are shown below:
Select
Inputs

Za e I0a # S1 # S0 a I1a # S1 # S0 a I2a # S1 # S0 a I3a # S1 # S0
Zb e I0b # S1 # S0 a I1b # S1 # S0 a I2a # S1 # S0 a I3b # S1 # S0
The 93L09 is frequently 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 93L09 can generate two functions of
three variables. This is useful for implementing random gating functions.
