The keyboard inputs may be used with either a standard 5 ×
I 5 keyboard or an inexpensive single contact (Form A)
keyboard. Electronic input from a µC can also be used.
A valid key is defined as a single row being connected to a
single column.
XT, XT
7, 8
7, 8 I, O A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal or ceramic resonator.
T/P MUTE
9
9
O The T/P MUTE is a conventional CMOS N-channel open
drain output.
The output transistor is switched on during dialing sequence
and flash break time. Otherwise, it is switched off.
MODE
13
15
I Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD places the dialer in pulse mode
(M/B = 40:60).
Floating mode pin places the dialer in pulse mode
(M/B = 33.3:66.7).
HKS
10
12
I Hook switch input.
HKS = VDD: On-hook state. Chip in sleeping mode, no
operation.
HKS = VSS: Off-hook state. Chip enabled for normal
operation.
HKS pin is pulled to VDD by an internal resistor.
