Function
1
V
CC1
Power input pin
Supply a voltage of 5 V
±
10% to this
pin. If the IC malfunctions due to power
noise, connect a bypass capacitor.
2
OUT
Output pin
An open-collector output pin (active
low) with a pull-up resistor (33 k
TYP.)
Connect an external pull-up resistor of
2.2 k
or more, if any, to this pin.
3
V
CC2
Power output pin
Connect a capacitor of 47
μ
F or so to
this pin to stabilize the supply voltage to
the internal circuit.

BPF frequency
setting pin
Sets the central frequency of the
internal bandpass filter by an external
resistance (refer to

in
CHARACTERISTIC CURVE
).
Use a resistor with excellent accuracy
and temperature characteristics.

GND pin
6
C
D
Detection
capacitor
connection pin
Connect a smoothing capacitor to this
pin to obtain a DC voltage corresponding
to the output signal level of the internal
bandpass filter.
The 0.01
μ
F is the most suitable value
for the external capacitor between pin 6
and GND. In case of reducing this
capacitor, confirm that the output pulses
from pin 2 have enough width even if
the longest burst signal is inputted.
