(2) The pullup/pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The pulsed output current rating is the
combined current from the bipolar and MOSFET transistors.
(3) The pullup/pulldown circuits of the driver are bipolar and MOSFET transistors in parallel. The output resistance is the R
DS(ON)
of the
MOSFET transistor when the voltage on the driver output is less than the saturation voltage of the bipolar transistor.
