IL5851 - Pulse Dialer with Redial

Description

NAME VCC PIN 1 Positive supply pin.

The voltage on this pin is measured relative to Pin 6 and is supplied from a 150µA current source.

This voltage should be regulated to less than 6.0 volts using on external form or regulation.

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 IL5851.
