* Stresses beyond those listed above may cause permanent damage to the device. These are stress

ratings only and functional operation of the device at these or any other conditions beyond those

indicated under the recommended operating conditions is not implied. Exposure to absolute

maximum rated conditions for extended periods of time may affect device reliability.

Note:

(1) Any D terminal from Gnd or to VCC

(2) Total through all Gnd or VCC terminals

(3) These values apply for tW=100

µs, duty cycle ≤ 20%

(4) For operation above 25°C , derate linearly at the rate of 6.25mW/°C
