The keyboard inputs may be used with either a standard
5
×
4 keyboard or an inexpensive single contact (Form A)
keyboard. Electronic input from a
μ
C can also be used.
A valid key 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
W91342N/W91342AN = 20 ppS.)
Floating mode pin places the dialer in pulse mode with M/B
ratio of 33.3:66.7 (10 ppS, except for W91342N/W91342AN
= 20 ppS.)
Hook switch input.
