*Negative power supply pin. *Positive power supply pin. *Hook switch input pin. *When handset ON-HOOK state, this must pulled "high" order disable dialing operation decrease power consumption. *When OFF-HOOK state, must pulled "low" state function operation. *Pulse output signal pin. *Inverter output structure (SC91650).
*The output "LOW" during pulse dialing Flash operation, otherwise this output "high". *NMOS open drain output structure. *Dual Tone Multi-frequency output pin. TONE mode, when entry digit (include key), this will send corresponding DTMF signal.
TONE
*The TONE provides minimum tone duration (tTD) minimum intertone pause time support rapid key-in. key-in time less than (100ms), DTMF signal will last (100ms); otherwise tone duration will last long pressed. *Mode select pin.
