keyboard or an inexpensive single contact (Form A) keyborad.
Electronic input from a
μ

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.

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.
MODE
13
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 with M/B ratio
40:60
(20 ppS only for W91433N and 10 ppS for the others, M/B = 40:60).
Floating mode pin places the dialer in pulse mode with M/B ratio 33:67
(20 ppS only for W91433N and 10 ppS for the others).
