UTCTA31002 - TELEPHONE TONE RINGER

General Description

The UTC TA31002 is a bipolar integrated circuit designed for telephone bell replacement.

It can also be used as alarms or other alerting devices.

Key Features

  • Current consumption is small. (at no-load).
  • Package is compaction. (DIP-8 pin).
  • Oscillation frequency is variable.
  • Built-in threshold circuits prevent false triggering due to power noise as well as “chirps” due to rotary dial.
  • Few external componens. DIP-8 PIN.
