The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:

The V
and is rated for 4.5V to 18V 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 minimum value of 1.0 µF is suggested.
3.2
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
The MOSFET driver output is a low-impedance,
CMOS, push-pull style output capable of driving a
capacitive load with 9.0A peak currents. The MOSFET
driver output is capable of withstanding 1.5A peak
reverse currents of either polarity.
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.
3.5
The exposed metal pad of the 6x5 DFN package is not
internally connected to any potential. Therefore, this
pad can be connected to a ground plane or other
copper plane on a printed circuit board to aid in heat
removal from the package.
