pin FuncTions
GND (PIN 1): Ground.
INPUT
+
(PIN 2): Non-Inverting Input of Comparator
INPUT
–
(PIN 3): Inverting Input of Comparator
V
–
(PIN 4): Negative Supply Voltage
OUT (PIN 7): Open-Collector Output of Comparator
BALANCE (PIN 5): Balance Input. This input can be used
to adjust the input voltage offset or to add hysteresis. If
offset balancing or hysteresis is not used, the BALANCE
pins should be connected together with a 0.1µF capacitor.
BALANCE/STROBE (PIN 6): Strobe Input Pin. Using this
pin, the output transistor can be forced to an “off” state,
giving a “hi” output at the collector (Pin 7). This input can
be used to adjust the input voltage offset or used to add
hysteresis. If offset balancing or hysteresis is not used,
the BALANCE pins should be connected together with a
0.1µF capacitor.

(PIN 8): Positive Supply Voltage
