A heatsink is required to keep the junction temperature below absolute maximum rating when an output is heavily loaded or shorted.
See Absolute Maximum Ratings section for more information.
Approximately 0.5 mA (total) flows from V
to GND for internal logic control bias.
Slew rate is defined from the 25% to the 75% output levels.
