This allows the insertion of drain-current-limiting resistors in the pull-up and/or pulldown sections, allowing the user to define the rates of rise and fall for a capacitive load; or a reduced output swing, if driving a resistive load, or to limit base current, when driving a bipolar transistor.
Minimum rise and fall times, with no resistors, will be less than 30 nsec for a 1000-pF load.
There is no upper limit.
For driving MOSFETs in motor-control applications, where slow-ON/fast-OFF operation is desired, these devices are superior to the previously-used technique of adding a diode-resistor combination between the driver output and the MOSFET...
