REV. C
Maximum ratings are limiting values to be applied individually, and beyond which
the serviceability of the device may be impaired. Functional operation under any of
these conditions is not necessarily implied. Exposure to absolute maximum rating
conditions for extended periods of time may affect device reliability.
Applied voltage must be current-limited to specified range.
Forcing voltage must be limited to specified range.
Current is specified as negative when flowing into the device.
Output High; one pin to ground; one second duration.
Typical thermal impedances (no air flow) are as follows:
