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.
3VCC 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.
