Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. T his is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
2
T ransient currents of up to 100 mA will not cause SCR latch-up.
