HBS-Compatible Driver and Receiver
Monolithic IC MM1192
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. AMI is adopted for the waveforms of signals handled by
the transmission and reception units, designed for connection to twisted-pair lines.
The IC can be driven by a single 5V power supply, and incorporates an output transistor to reduce the
number of external components required.
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. Can be driven by a single 5V power supply
5. Low cost
6. Easy circuit design
7. 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

When a negative voltage is applied to pins 7, 8, 9 and 10, 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.
-
In addition, no measures have been taken for a negative voltage at pins 12 and 14. Hence if a negative
voltage is applied to pins 12 and 14, the internal transistor should not be used.

Circuit Diagram
Note 1: The peripheral components in the block diagram are the constants for Ftransmit=10kHz. If the
frequency is low, larger values should be chosen for the coupling capacitors between the receive and
transmit pins and the bus line and for the capacitor connecting pins 3 and 4.
Note 2: A block diagram is shown for an example application in which an external transistor is used; but
depending on system conditions the internal transistor may be used, and no external transistor is
needed. In such cases pins 7 and 8 are left open, a 1Ω resistance is inserted between pins 10 and 12,
and a 1Ω resistance is inserted between pins 9 and 14.
When the load resistance (36Ω) is to be varied during use, these resistances (1Ω) should be changed
according to the load resistance. If these resistances are omitted, oscillation may occur at low volume
levels.
