I
The keyboard input may be from either the standard 4
× 4
keyboard or an inexpensive single contact (form A) keyboard.
Electronic input from a
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.
T/P
MUTE
9
10
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.
MODE
13
14
I
Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD places the dialer in pulse mode (10
ppS). Leaving mode pin floating places the dialer in pulse
mode (20 ppS).
HKS
10
11
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 VDD by an
internal resistor.
DP
11
12
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.
