Pin Configuration
Functional Description
Power Supply, Pin 8
For reasons of interference protection and surge immu-
nity, the supply voltage (Pin 8) must be provided with an
RC circuit as shown in figure 3. Dropper resistor, R
limits the current in case of overvoltage, whereas C
smoothes the supply voltage at Pin 8.
Recommended values are: R

The integrated Z-diode (14 V) protects the supply volt-
age,V
between 6 V and 16 V, supplied by V
However, it is possible to operate the integrated circuit
with a 5 V supply, but it should be free of interference
voltages. In this case, Pin 7 is connected to Pin 8 as shown
