Power Supply (Pin 8)
For reasons of interference protection and surge immunity, the supply voltage (pin 8) must be
provided with an RC circuit as shown in
case of overvoltage, whereas C
Recommended values are: R
The integrated Z-diode (14V) protects the supply voltage, V
is possible between 6V and 16V, supplied by V
However, it is possible to operate the integrated circuit with a 5V supply, but it should be free of
interference voltages. In this case, pin 7 is connected to pin 8 as shown in
and the R
