HBS-Compatible Driver and Receiver
Monolithic IC MM1007
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. 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

When a negative voltage is applied to pins 10 and 11, 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.
