1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
2. V
IN
minimum = –3.0V for pulse width less than 15ns.
V

+0.5V.
3. Not more than one output should be shorted at a time. Duration of the short
should not exceed 30 seconds.
