Absolute Maximum Ratings(1, 2)

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.

Note:

1.These ratings are based on a maximum junction temperature of 150°C.

2.These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle

operations.
