Establishing Static Logic Inputs

The true pin of an input pair is internally biased to ground

through a 75k

Ω resistor. The complement pin of an input

pair is internally biased halfway between V

by a voltage divider consisting of two 75k

Ω resistors. To

keep an input at static logic zero at V

inputs unconnected. For V

complement input to V

unconnected. To make an input static logic one, connect

the true input to V

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.
