ITT9312
MSI Eight-Input Multiplexer
FUNCTIONAL DESCRIPTION - The ITT9312 is
a logical implementation of a single pole - 8
position switch with the switch position
controlled by the state of three select inputs,
80, 81, 82. Both assertion and negation
outputs are provided. The enable input (E) is
active low. When it is not activated the
negation output is high and the assertion
output is low regardless of all other outputs.
The ITT9312 provides the ability, in one
package, to select from eight sources of data or
control information. By proper manipulation of
the inputs, the ITT9312 can provide any logic
fuhction of four variables and its negation.
Thus any number of random logic. elements
used to generate unusual truth tables can be
replaced by one ITT9312.
