The keyboard input may be from either the standard 4
×
5 keyboard or an inexpensive single contact (form A)
keyboard. Electronic input from a
μ
C can also be used. A
valid key entry is defined by a single row being
connected to a single column.

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 sequences and flash break.
Otherwise, it is switched off.

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
(10 ppS, M/B = 2:3). If the mode pin is left floating, the
dialer is in pulse mode (10 ppS, M/B = 1:2).
