Notes:

1. Stresses greater than those listed under MAXIMUM 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 above

those indicated in the operational sections of this specification is not

implied. Exposure to MAXIMUM rating conditions for extended periods

may affect reliability

2. Extended temperature operation guaranteed with 400 linear feet per minute

of air flow.

3. Fortestpurposes,notmorethanoneoutputatatimeshouldbeshorted.Short

circuit test duration should not exceed 30 seconds.

4. This parameter is sampled and not 100% tested.
