Establishing Static Logic Inputs
through a 75k
pair is internally biased halfway between V
by a voltage divider consisting of two 75k
way, unconnected inputs appear as logic zeros. To keep an
input at static logic zero at V

FUNCTIONAL DESCRIPTION
The true pin of an input pair is internally biased to ground
X is either D0 or D1 input. /X is either /D0 or /D1 input.

the complement input unconnected. These are the only two
safe ways to cause inputs to be at a static value. In particular,
no input pin should be directly connected to ground. All NC
(no connect) pins should be unconnected.
