3.1 Supply Input (VDD)
The VDD input is the bias supply for the MOSFET driver
and is rated for 4.5V to 16V with respect to the ground
pin. The VDD input should be bypassed to ground with
a local ceramic capacitor. The value of the capacitor
should be chosen based on the capacitive load that is
being driven. A value of 1.0 µF is suggested.
3.2 Control Input (INPUT)
The MOSFET driver input is a high-impedance,
TTL/CMOS-compatible input. The input also has
300 mV of hysteresis between the high and low
thresholds that prevents output glitching even when the
rise and fall time of the input signal is very slow.

3.3 CMOS Push-Pull Output
(OUTPUT)
The MOSFET driver output is a low-impedance,
CMOS, push-pull style output, capable of driving a
capacitive load with 0.5 A peak currents.
3.4 Ground
The ground pins are the return path for the bias current
and for the high peak currents that discharge the load
capacitor. The ground pins should be tied into a ground
plane or have very short traces to the bias supply
source return.
