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
Positive power supply (5% tolerance).
V_EE
Negative power supply (5% tolerance).
V_EXT
External 5.5VDC power supply (5.5VDC to 6.0VDC as referenced to V_EE, NOT GND. Recommended V_EXT = 5.5V) for internal
logic. Connect pin to V_EE when not using an external supply.
LOWSWING 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 LOWSWING to V_EE to select low swing circuitry, or connect it to V_CC to select high
swing circuitry.
