PIN FUNCTIONS
UUU
IN (Pin 1): Driver Input. The input has V
CC
independent
thresholds with hysteresis to improve noise immunity.
NC (Pins 2, 5, 6): No Connect.
PHASE (Pin 3): Output Polarity Select. Connect this pin to
V
CC
or leave it floating for noninverting operation. Ground
this pin for inverting operation. The typical PHASE pin
input current when pulled low is 20µA.
GND (Pin 4): Driver Ground. Connect to a low impedance
ground. The V
CC
bypass capacitor should connect directly
to this pin.
OUT (Pin 7): Driver Output.
V
CC
(Pin 8): Power Supply Input. The source of the exter-
nal P-MOSFET should also connect directly to this pin.
This minimizes the AC current path and improves signal
integrity.
