PIN DESCRIPTION
Symbol C1 C2 C3 C4 Function Provides keyboard scanning . a. Keyboard scanning: HKS pin is LOW, the column group stays in "HIGH" stays and row group stays in "LOW" state. The key pad is compatible with the standard dual contact matrix keyboard (as Figure 1b.), the inexpensive single contact keyboard (as Figure 1a.), and electronic input (as Figure 1c.). When HKS is "low", a valid key entry is defined by related Row & Column connection or by electronic input; (as show in Figure 1c). Activation of two or more keys will result in no response, except for single key. To avoid keyboard bouncing error, this chip provides built-in debounce circuit. (The debounce time = 20 ms.)

Figure 1c : Electronic signal input keyboard configuration OSCI OSCO Oscillator input & Oscillator output pins. The 3.579545 MHz oscillator is formed by a built-in inverter inside of this chip and by connecting a 3.579545 MHz crystal or a ceramic resonator across the OSCI and OSCO pins. (built-in feedback resistor and capacitor) When HKS is "low", a valid key-in may turn on this oscillator and generates a 3.579545 MHz clock. Mute output pins. NMOS open drain output structure. The output is in "low" state during dialing sequence (both Pulse and Tone mode) otherwise this pin is "high-impedance" . Long (continue) Mute. Negative power supply pin. Positive power supply pin. Hook switch input pin. When the handset is in ON-HOOK state, this pin must be pulled "high" in order to disable the dialing operation and decrease the power consumption. When in OFF-HOOK state, the HKS pin must be pulled "low" state for all function operation. Pulse output signal pin. NMOS open drain output structure. The output is "low" during pulse dialing and Flash operation, otherwise this output is "floating".

TONE/PULSE SWITCHABLE DIALER
Symbol TONE
Function Dual Tone Multi-frequency output pin. In TONE mode, when a entry of digit key (include * , # key), this pin will sent out a corresponding DTMF signal. The TONE pin provides minimum tone duration (tTD),& minimum intertone pause time to support rapid key-in. If key-in time is less than tTD , DTMF signal will last for tTD , otherwise the tone duration will last as long as the key is pressed. Handfree input control pin. Toggle input sturcture, falling edge trigger. It is used to enable and disable Handfree function. With waveshaped by a built-in Schmit trigger, the bounce of input can be eliminated by external R, C debounce circuit. A built-in pull up resistor is 200K typical. Handfree output pin. Inverter output structure (normally "low", active "high"). When a HFI pin is active, Handfree function will be enabled (HFO=1) or disabled (HFO=0). When the Handfree function is enable (HFO=1), after OFF-HOOK action, it can reset Handfree function and HFO pin return to "low" state.
