Establishing Static Logic Inputs
The true pin of an input pair is internally biased to ground
through a 75k
resistor. The complement pin of an input
pair is internally biased halfway between V
CC
and ground
by a voltage divider consisting of two 75k
resistors. To
keep an input at static logic zero at V
CC
> 3.0V, leave both
inputs unconnected. For V
CC
3.0V, connect the
complement inputs to V
CC
and leave the true inputs
unconnected. To make an input static logic one, connect
the true input to V
CC
, leave the complement input
unconnected. These are the only 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.
