Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-

ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-

tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The

absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Notes:

1. Thermal resistance test board

Size: 1.6mm x 76.2mm x 114.3mm (1S0P)

JEDEC Standard: JESD51-3, JESD51-7.

2. Assume no ambient airflow.

3. TJMAX = 150

°C; Ratings apply to ambient temperature at 25°C.

4. Power dissipation calculation: PD = (TJ - TA) / RθJA.

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to Absolute Maximum Ratings.
