Parameters
Pin Symbol
Function
1
A_I Inverting input of bandpass
amplifier, pin connection for
external filter function
2
A_O 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
O_SW 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
V_S Supply voltage
The integrated Z-diode (typically
17 V) protects the circuit against
positive voltage spikes
6 GND Ground
7
V_S1 Unregulated supply voltage for
5 V operation
8
IN Input connection for photodiode
with regulated bias voltage
