TECHNICAL DATA

KK5851

PULSE DIALER WITH REDIAL

The KK5851 is a monolithic CMOS integrated circuit which uses an

inexpensive RC oscillator for its frequency reference and provides all the

features required for implementing a pulse dialer with 32 digit redial.

•

Wide operating voltage range (2.0~6.0V)

Low power dissipation

Use either a standard 2 of 7 matrix keyboard with negative true common

or the inexpensive form A-type keyboard

Make/Break ratio can be selected

Redial with * or #

Continuous MUTE

Power up clear circuitry on chip

10 pps/20 pps can be selected
