The keyboard input may be from either the standard 4
×
4 keyboard or an inexpensive single contact (form A)
keyboard. Electronic input from a
μ
C can also be used. A
valid key entry is defined as a single row being
connected to a single column.
I, O A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal or ceramic resonator.
O
The T/P MUTE is a conventional CMOS N-channel open
drain output. The output transistor is switched on during
pulse and tone mode dialing sequence and flash break.
Otherwise, it is switched off.
I
Pulling mode pin to V
SS
places the dialer in tone mode.
Pulling mode pin to V
DD
places the dialer in pulse mode
(10 ppS). Leaving mode pin floating places the dialer in
pulse mode (20 ppS).
I
Hook switch input. HKS = 1: On-hook state. Chip in
sleeping mode, no operation. HKS = 0: Off-hook state.
Chip enabled for normal operation. The HKS pin is
pulled to V
DD
by an internal resistor.
O
N-channel open drain dialing pulse output (Figure 1).
Flash key will cause DP to go active in both pulse mode
and tone mode.

In pulse mode, remains in low state at all times. In tone
mode, outputs a dual or single tone. Detailed timing
diagram for tone mode is shown in Figure 2(a, b).
