PULSE DIALER WITH REDIAL
TECHNICAL DATA
IN5851
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.
⢠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
