The keyboard inputs may be used with either a standard
5
×
5 keyboard or an inexpensive single contact (Form A)
keyboard. Electronic input from a
μ
C can also be used.
A valid key in is defined as a single row being connected to
a single column.
A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal or ceramic resonator.

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.
Pulling mode pin to V
SS
places the dialer in tone mode.
Pulling mode pin to V
DD
places the dialer in pulse mode
with M/B ratio of 40:60 (10 ppS, except for
W91352N/352AN = 20 ppS).
Floating mode pin places the dialer in pulse mode with M/B
ratio of 33.3:66.7 (10 ppS, except for W91352N/352AN =
20 ppS).
Hook switch input.
HKS = V
DD
: On-hook state. Chip in sleeping mode, no
operation.
HKS = V
SS
: Off-hook state. Chip is enabled for normal
operation.
HKS pin is pulled to V
DD
by an internal resistor.
