NOTES:

1. Ensured by design. Not tested in production.

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

combined current from the bipolar and MOSFET transistors.

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

5. See Figure 2.
