General 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.
Key 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.
