I

The keyboard input is compatible with a standard

6

× 6 or 7 × 7 keyboard, an inexpensive single

contact (Form A) keyboard, and electronic input.

In normal operation, any single button can be

pushed to produce dual tone, pulses, or functions.

Activation of two or more buttons will result in no

response except for a single tone.

I

A built-in inverter together with an inexpensive

3.579545 MHz crystal supplies the oscillator. The

oscillator stops when there is no keypad input.

The crystal frequency deviation is 0.02%.

Crystal oscillator output pin.

T/P MUTE

12

O

The T/P MUTE is a conventional CMOS N-

channel open drain output.

The output transistor turns on with a low level

during a dialing sequence (both pulse and tone

mode). Otherwise, it is off.

K MUTE

22

O

The K MUTE is a conventional CMOS N-channel

open drain output.

Toggle action speech mute control pin by MUTE

key.

MODE

20

I

Connecting the mode pin to VSS places the dialer

in tone mode.

Connecting the mode pin to VDD places the dialer

in pulse mode with an M/B ratio of 40:60.

Leaving the mode pin floating places the dialer in

pulse mode with an M/B ratio of 33.3:66.7.

HKS

17

I

The HKS (hook switch) input is used to sense

whether the handset is on-hook or off-hook.

In on-hook state, HKS = 1: chip is in sleeping

mode, no operation.

In off-hook state, HKS = 0: chip is enabled for

normal operation.

HKS pin is pulled to VDD by internal resistor.
