Pin 12 (AUDIO OUT)
12
Terminal voltage: 2.2 V
In the 4.5 MHz application, the internal voltage gain is
increased by 6-dB in comparison with the other applications
and then the signals are delivered through an emitter
follower.

It works as a switch by connecting the resistor to 5 V (High)
or GND (Low), alternately.

The terminal voltage is set by the external resistors because
of an open base input.
Pin 15 (QIF OUT)

: 0.5 mA.
Terminal voltage: 2.45 V

In both the split and intercarrier system, the carrier signal to
SIF provided from pin 15 through an emitter follower.

The recommended supply voltage is 5 V or 9 to 12 V.
In the case of 5 V supply, these pins should be tied to pin 20
and pin 21.
In the case of 9 to 12 V supply, a regulated output of 5 V are
available in pin 20 and pin 21.
