Description
The IN5851 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.

Features
• 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
