The keyboard inputs may be used with either a standard
I 5 × 5 keyboard or an inexpensive single contact (Form A)
keyboard. Electronic input from a µC can also be used.
A valid key in is defined as a single row being connected to
a single column.
7, 8 I, O A built-in inverter provides oscillation with an inexpensive
3.579545 MHz crystal or ceramic resonator.

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.
15 I Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD 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).
12 I Hook switch input.
HKS = VDD: On-hook state. Chip in sleeping mode, no
operation.
HKS = VSS: Off-hook state. Chip is enabled for normal
operation.
HKS pin is pulled to VDD by an internal resistor.
