The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
MOSFET driver inputs A and B are high-impedance,
TTL/CMOS compatible inputs. These inputs also have
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.
3.2
Ground is the device return pin. The ground pin(s)
should have a low-impedance connection to the bias
supply source return. High peak currents will flow out
the ground pin(s) when the capacitive load is being
discharged.
3.3
MOSFET driver outputs A and B are low-impedance,
CMOS push-pull style outputs. The pull-down and pull-
up devices are of equal strength, making the rise and
fall times equivalent.

ceramic capacitors. The value of these capacitors
should be chosen based on the capacitive load that is
being driven. A value of 1.0 F is suggested.
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.
