NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the

device at these or any other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

2Transient currents of up to 100 mA will not cause SCR latch-up.

3V

CC must not exceed VDD by more than 0.3 V. If it is possible for this to happen

during power supply sequencing, the following diode protection scheme will ensure

protection.
