Power supply pin.
Function
Used to generate the reference frequency.
Uses a crystal resonator of 3.579545MHz.
With the feedback resistor and capacitors contained to form
the OSC circuit, a crystal resonator is simply connected
across the pins.
When using a ceramic resonator, a capacitor of
approximately 30pF must be connected to each pin.

Row and column input pin. High-active input.
Contains a P-channel transistor for keyboard scan and an N-
channel transistor for pull-down.
When in the ON-HOOK state, the P-channel transistor is
turned OFF and the N-channel transistor is turned ON.
HOOK SW input.

Dial pulse output.
Mute output. Operates at the OUTPUT-PULSE mode.
Capable of being wired-ORed with MUTE2.
Mute output. Operates at the DTMF mode. Capable of being
wired-ORed with MUTE1.
DTMF/OUTPUT-PULSE mode output.
OUTPUT-PULSE mode=L-level
DTMF mode=H-impedance
When a key is pushed at the OUTPUT-PULSE mode, the K-
TONE (pacifier tone) of 1243Hz/50ms is output.
The DTMF signal is output.
NPN transistor-used emitter follower output.
