Pin Descriptions
PIN
FUNCTION
DATA+(0:3) Positive differential digital input that determines the driver output state when it is enabled.
DATA-(0:3) Negative differential digital input that determines the driver output state when it is enabled.
DRV EN+(0:3) Positive differential digital input that enables or disables the corresponding driver.
DRV EN-(0:3) Negative differential digital input that enables or disables the corresponding driver.
QA (0:3) Comparator digital outputs. QA(X) is high when VINP(X) exceeds CVA(X).
QB (0:3) Comparator digital outputs. QB(X) is high when VINP(X) exceeds CVB(X).
DOUT (0:3) Driver outputs.
VINP (0:3) Comparator inputs.
VH (0:3) Unbuffered analog inputs that set each individual driver’s “high” voltage level.
VL (0:3) Unbuffered analog inputs that set each individual driver’s “low” voltage level. VL must be a lower voltage than VH.
NC
No internal connection.
CVA (0:3) Analog inputs that set the threshold for the corresponding channel’s A comparators.
CVB (0:3) Analog inputs that set the threshold for the corresponding channel’s B comparators.
COMP HI Supply voltage, unbuffered input that sets the high output level of all comparators. Must be greater than COMP LO.
COMP LO Supply voltage, unbuffered input that sets the low output level of all comparators. Must be less than COMP HI.
V_CC
V_EE
V_EXT
Positive power supply (5% tolerance).
Negative power supply (5% tolerance).
External 5.5VDC power supply (-0%+5% tolerance, referenced to V_EE, NOT GND) for internal logic. Connect pin to V_EE when
not using an external supply.
LOSWING
Input that selects driver output configurations optimized to yield minimum overshoots for low level swings (VH < V_EE +5V), or
optimized for large output swings. Connect LOSWING to V_EE to select low swing circuitry, or connect it to V_CC to select high
swing circuitry.
