Pin Descriptions
PIN SYMBOL
DESCRIPTION
1
GND Ground pin. Sets the Comparator output
low level.
2
V-
Negative Supply Input for Voltage
Reference and Comparator.
3
IN+ Comparator non-inverting input pin.
Range: V- to V+ -1.5V.
4
IN- Comparator inverting input pin. Range: V-
to V+ -1.5V
5
HYST Comparator Hysteresis input. Accepts a
voltage divided from the Reference
output. Range is VREF - 50mV to VREF.
Connect directly to VREF for zero
hysteresis.
6
REF Reference output. Source 2mA and Sink
10µA.
7
V+ Positive Supply Input for Comparator and
Reference. Range is 2.0V to 11.0V
8
OUT Comparator output, CMOS push-pull.
Output swing referenced to V+ and GND.
