3.0
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
MOSFET drivers IN A & 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
GND 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 of the
ground pin(s) when the capacitive load is being
discharged.

3.3
MOSFET drivers OUT A & 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 µF is suggested.
