The ADM483 is a low power differential line transceiver suitable
for half-duplex data communication on multipoint bus transmission
lines. It is designed for balanced data transmission, and
complies with EIA Standards RS-485 and RS-422.The part
contains a differential line driver and a differential line receiver.
Both share the same differential pins, with either the driver or
the receiver being enabled at any given time.
The device has an input impedance of 12 kΩ, allowing up to
32 transceivers on one bus. Since only one driver should be
enabled at any time, the output of a disabled or powered-down
driver is three-stated to avoid overloading the bus. This high
impedance driver output is maintained over the entire
common-mode voltage range from –7 V to +12 V.
