thus minimizing chip count. Unused open drains should be

returned to the supply rail that their device sources are

prevent static damage. In addition, in situations where

timing resistors or other means of limiting crossover currents

are used, like drains may be paralleled for greater current

carrying capacity.

These devices are built to operate in the most de-

manding electrical environments. They will not latch up

under any conditions within their power and voltage rat-

ings; they are not subject to damage when up to 5V of

noise spiking of either polarity occurs on their ground pin;

and they can accept, without damage or logic upset, up to

1/2 amp of reverse current (of either polarity) being forced

back into their outputs. All terminals are fully protected

against up to 2 kV of electrostatic discharge.

*Static-sensitive device. Unused devices must be stored in conductive

material. Protect devices from static discharge and static fields. Stresses

above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. These are stress ratings only and functional

operation of the device at these or any other conditions above those

indicated in the operational sections of the specifications is not implied.

Exposure to Absolute Maximum Rating Conditions for extended periods

may affect device reliability.
