Description
CMOS
I/O
These pins along with the HKS form a 4´4 keyboard matrix which can perform keyboard input detection. 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.

Functional Description
Keyboard matrix
Flash
C1~C3, HKS and R1~R4 form a keyboard matrix. Together with a standard 4´4 keyboard, the keyboard
matrix is used for dialing entries. The keyboard arrangement of the HT93214 series is shown in the Keyboard Information.
Two flash keys are provided, namely F1, F2 for both series. All the flash key function as control key with different break duration. Whenever a flash key is pressed the
PO pin will be forced low for a TF duration and the transmission of the new digit key inputs will be further delayed for a TFP after TF. See the following table for flash
duration selection.

· F1, F2
Pressing one of the flash keys will force the PO pin to
become low for the TF duration. To transmit the dial
signals of the key input that are entered after the F
key, a wait period TFP (sec) after PO pin returns from
low is provided.
· The MODE pin status is checked whenever a digit key
is pressed, however the M/B and pulse rate are determined at the first key entry.
· P
Pause key. The execution of this key pauses the output for the TP duration (2.2s).
