FUNCTION
The keyboard input may be from either the
standard 9
×
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.
I, O 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
pulse and tone mode dialing sequence and
flash break. Otherwise, it is switched off.
O The HPM MUTE is a conventional inverter
output. During pulse dialing, flash, hold, and
mercury mute functions, this pin will output
an active high. It remains in a low state at all
other times.
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 (M/B = 2:3).
Leaving mode pin floating places the dialer
in pulse mode (M/B = 1:2).
I
Hook switch input.
HKS = 1: On-hook state. Chip in sleeping
mode, no operation.
HKS = 0: Off-hook state. Chip enabled for
normal operation.
HKS pin is pulled to V
DD
by internal resistor.
O N-channel open drain dialing pulse output
(Figure 1).
Flash key causes DP to go active when in
pulse mode and tone mode.
