| MITSUMI HBS-Compatible Driver and Receiver with Power Supply MM1034 HBS-Compatible Driver and Receiver with Power Supply Monolithic IC MM1034 Outline This IC conforms to the HBS (Home Bus) specification (Electronic Industries Association of Japan), and has functions for the reception and transmission of data. It incorporates power supply circuitry which employs an efficient switching regulator, and so can draw power directly from the bus line. AMI is adopted for the waveforms of signals handled by the transmission and reception units, designed for connection to twisted-pair lines. Telephone equipment, security devices, audio or video equipment, air-conditioning equipment, and a wide range of other devices can be connected to a bus line to enable mutual communications. Features 1. Compact design 2. High reliability 3. Replaces pulse transformers 4. Low cost 5. Adopts highly efficient switching regulator 6. Easy circuit design 7. Stable internal power supply circuit (Vo1=5 V 0.25) 8. Few external components Applications 1. Telephony equipment 2. Security equipment 3. Audio and video devices 4. Air-conditioning equipment 5. Wide range of other equipment and devices Package DIP-16A (MM1034XD) SOP-16A (MM1034XF) Block diagram MITSUMI HBS-Compatible Driver and Receiver with Power Supply MM1034 Absolute Maximun Ratings Item Storage temperature Operating temperature Power supply current (Ta=25C) Symbol TSTG TOPR VCC max.

However, if a negative voltage exceeding -6V is applied, thyristor operation may result, so it is recommended that an external clamping diode be added.
