The V
and is rated for 4.5V to 16V with respect to the ground
pin. The V
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
The MOSFET driver input is a high-impedance,
TTL/CMOS-compatible input. The input has 300 mV of
hysteresis between the high and low thresholds which
prevents output glitching even when the rise and fall
time of the input signal is very slow.

3.3
The MOSFET driver output is a low-impedance, CMOS
push-pull style output, capable of driving a capacitive
load with 2A peak currents.
3.4
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.
