FUNCTIONAL DESCRIPTION
The ITT9309 dual four input multiplexer is a
member of the ITT family of compatible
Medium Scale Integrated (MSI) digital building
blocks. It provides this family with the ability to
select two bits of either data or control from up
to four sources, in one package.
The ITT9309 dual four input multiplexer is the
logical implementation of a two-pole fourposition
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:
A common use of the ITT9309 would be the
moving of ,data from a group of registers to a
common output buss. The particular register
from which the data came would be determined
by the state of the select inputs, A less obvious
use is as a function generator. The ITT9309 can
generate any two functions of three variables.
This is useful for implementing random gating
functions.
