Precautions
1.
The voltage applied to comparator input pins 6 and 7
should not be allowed to go below ground by more
than 0.3V.
2.
Pins 3 and 5 are open-collector outputs. Shorts
between these pins and V
CC
can cause overheating
and eventual destruction.
3.
Reference voltage terminal pin 2 is connected to the
emitter of an NPN transistor and is held at
approximately 1.9V. This terminal should be
protected from accidental shorts to ground or supply
voltages. Permanent damage may occur if the
current in pin 2 exceeds 5mA.
4.
Avoid stray coupling between pins 5 and 7; it could
cause false triggering. For the circuit of Figure 2
bypass pin 7 to ground with at least 0.01
μ
F. This is
necessary for operation above 10kHz.
