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

I, O
A built-in inverter provides oscillation with an inexpensive 3.579545
MHz crystal or ceramic resonator.
T/P MUTE
8
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.
MODE
4
I
Pulling mode pin to VSS places the dialer in tone mode.
Pulling mode pin to VDD 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).
