Function

1

AI Inverting input of bandpass

amplifier, pin connection for

external filter function

2

AO Output of bandpass amplifier

3

C3 Capacitor at Pin 3 to reject

(suppress) ripple during trans-

mission, also functions as delay

time for reference voltage of the

comparator

4

OSW Switching output

Open collector output which

switches with time delay and

turns to LOW (transistor

switched ON) when the signal is

identified at Pin 2.

5

VS Supply voltage

The integrated Z-diode (typically

17 V) protects the circuit against

positive voltage spikes

6 GND Ground

7

VS1 Unregulated supply voltage for

5 V operation

8

IN Input connection for photodiode

with regulated bias voltage
