Driver Inputs. The inputs have VCC
IN (Pin 1):
Driver Input. The input has VCC independent independent thresholds with 1.2V typical hysteresis to thresholds with hysteresis to improve noise immunity. improve noise immunity.
NC (Pins 2, 5, 6):

Driver Grounds. Connect to a
PHASE (Pin 3):
Output Polarity Select. Connect this pin to low impedance ground. The VCC bypass capacitor should V connect directly to this pin. The source of the external CC or leave it floating for noninverting operation. Ground this pin for inverting operation. The typical PHASE pin MOSFET should also connect directly to the ground pin. input current when pulled low is 20µA. This minimizes the AC current path and improves signal integrity. The ground pins should not be tied together if
GND (Pin 4):
Driver Ground. Connect to a low impedance isolation is required between the two drivers of the ground. The VCC bypass capacitor should connect directly LTC1693-1 and the LTC1693-2. to this pin. The source of the external MOSFET should also connect directly to the ground pin. This minimizes the AC
OUT 1, OUT2 (Pins 5, 7):
Driver Outputs. The LTC1693- current path and improves signal integrity. 1’s outputs are in phase with their respective inputs (IN1, IN2). The LTC1693-2’s topside driver output (OUT1) is in
OUT (Pin 7):
Driver Output. phase with its input (IN1) and the bottom side driver’s
VCC (Pin 8):
Power Supply Input. output (OUT2) is opposite in phase with respect to its input pin (IN2).
VCC1, VCC2 (Pins 6, 8):
Power Supply Inputs.
