Notes:
1. All voltages referenced to SOURCE, T
2. Normally limited by internal circuitry.
3. 1/16 in. from case for 5 seconds.
4. Maximum ratings specified may be applied, one at a time,
Notes:
1. Measured on pin 2 (SOURCE) close to plastic interface.
2. Soldered to 0.36 sq. in. (232 mm
3. Soldered to 1 sq. in. (645 mm
