Absolute Maximum Ratings*

*NOTICE: Stresses beyond those listed under “Absolute Maxi-

mum 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 beyond those indicated in the

operational sections of this specification is not implied. Expo-

sure to absolute maximum rating conditions for extended peri-

ods may affect device reliability.

Note:

1.

Minimum voltage is -0.6V dc which may undershoot

to -2.0V for pulses of less than 20 ns. Maximum out-

exceeded if certain precautions are observed (con-

sult application notes) and which may overshoot to

+7.0 volts for pulses of less than 20 ns.
