When on-hook (HKS=high) all the pins are set high. While off-hook the column group (C1~C3) is set low and the row group (R1~R4) remains high for input detection. Pressing a key connects a single row to a single column HKS and actuates the system oscillator that results in a dialing signal output. If more than two keys are pressed at the same time, no response occurs. The key-in debounce time is 20ms. OSC The system oscillator consists of an inverter, a bias resistor and the necessary load capacitor on chip. Connecting a standard 3.579545MHz crystal or ceramic resonator to the X1 and X2 terminals can implement the oscillator function. The oscillator is turned off in the standby mode, and is actuated whenever a keyboard entry is detected. NMOS Open Drain NMOS open drain structure pulled to VSS during dialing signal transmission. Otherwise, it is an open circuit. This pin is used to mute the speech circuit when transmitting the dial signal. CMOS This pin is used to monitor the status of the hook-switch and its combination with HFI can control the PO pin output to make or break the line. HKS=VDD: On-hook state (PO=low). Except for HFI (hand-free control input), other functions are all disabled. HKS=VSS: Off-hook state (PO=high). The chip is in the stand-by mode and ready to receive the key input. NMOS NMOS open drain output structure, which by receiving the HKS and HFO signals, control the dialer so as to connect or disconnect the telephone line. PO is pulled to VSS when HKS is high (on-hook) and HFO is low. PO is an open circuit which make the line connection when HKS is low (off-hook) or HFO is high. During the off-hook state, this pin also outputs the dialing pulse train in pulse mode dialing. While in the tone mode, this pin is always an open circuit. CMOS This is a tri-state input/output pin, used for dialing mode selection, either Tone mode or Pulse mode, 10pps/20pps MODE=VDD: Pulse, 10pps, M/B=1/2 MODE=Floating: Pulse, 20pps, M/B=1/2 MODE=VSS: Tone. The MODE selection is checked each time a key input is received. DTMF O CMOS This pin is active only when the chip transmits tone dialing signals. Otherwise, it always outputs a low. The pin outputs tone signals to drive the external transmitter amplifier circuit. The load resistor (to VSS) should not be less than 5kW and any DC load connected to VDD is not allowed. KT O NMOS NMOS open drain structure for keytone output. It outputs 34ms of 600Hz tone burst when any key is pressed in the pulse mode or when a function key is pressed in the tone mode. HFI I CMOS Pulled-high, this pin is a Schmitt trigger input structure. Active low. Applying a negative going pulse to HFI can toggle the HFO once and hence control the hand-free function. The pull-high resistance of HFI is about 200kW typ. An external RC network is recommended for input debouncing. The HFO pin is a CMOS output structure. Its output is toggle- controlled by a negative transition on HFI pin. When HFO is high, the hand-free function is enabled and PO outputs a high to connect the line. The hand-free function can be released by an on-off-hook operation or by another HFI input. Refer to the functional description for the hand-free functional operation.
