HBS-Compatible Driver and Receiver with Power Supply
Monolithic IC MM1034
Features
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.
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

circuit
When a negative voltage is applied to pins 8 and 9, there should be no abnormal operation of internal circuits
between 0 and 6V. However, if a negative voltage exceeding
-
6V is applied, thyristor operation may result, so
it is recommended that an external clamping diode be added.

Additional Application Circuits
(SWR circuit not used)
Even when a 5V external voltage can be supplied, an addition voltage of 13 to 45V must be applied to pins 2
and 3 in order to obtain an internal biased power supply of 3.4V.
