NOTES:

2: Ensured by design, not production tested.

3: The pullup/pulldown circuits of the drivers are bipolar and MOSFET transistors in parallel. The peak output current rating is the

combined current from the bipolar and MOSFET transistors. The output resistance is the rDS(on) of the MOSFET transistor when

the voltage on the driver output is less than the saturation voltage of the bipolar transistor.
