Ground pin. Sets the Comparator output
low level.
Negative Supply Input for Voltage
Reference and Comparator.
Comparator non-inverting input pin.
Range: V- to V+ -1.5V.
Comparator inverting input pin. Range: V-
to V+ -1.5V
Comparator Hysteresis input. Accepts a
voltage divided from the Reference
output. Range is VREF - 50mV to VREF.
Connect directly to VREF for zero
hysteresis.
Reference output. Source 2mA and Sink
10µA.
Positive Supply Input for Comparator and
Reference. Range is 2.0V to 11.0V
Comparator output, CMOS push-pull.
Output swing referenced to V+ and GND.
