TECHNICAL DATA
PULSE DIALER WITH REDIAL
IL5851
The IL5851 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
