*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 indi-

cated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions

for extended periods 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

be exceeded if certain precautions are observed

(consult application notes) and which may over-

shoot to +7.0 volts for pulses of less than 20 ns.
