NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This 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.
2The outputs may be shorted to voltages in this range provided the power dissipation of the package is not exceeded.
3Transient currents of up to 100 mA will not cause SCR latch-up.
