Description
The UTC1240A are monolithic integrated circuits designed to replace the mechanical bell in telephone sets in connection with an electro-acoustical converter.Both devices can drive directly a piezoceramic converter (buzzer).
Features
- Low current consumptioin,in order to allow the parallel operation of 4 devices. against overvoltage.
- Little external circuitry.
- Tone and switching frequencies adjustable.
- Intergrated voltage and current hysteresis
