GENERAL DESCRIPTION
The ADM3483E/ADM3486E/ADM3488E/ADM3490E/
ADM3491E are 3.3 V, low power data transceivers with
±15 kV ESD protection suitable for full- and half-duplex
communication on multipoint bus transmission lines. They
are designed for balanced data transmission, and they
comply with TIA/EIA standards RS-485 and RS-422. The
ADM3483E/ADM3486E are half-duplex transceivers that
share differential lines and have separate enable inputs for
the driver and receiver. The full-duplex ADM3488E/
ADM3490E/ADM3491E transceivers have dedicated
differential line driver outputs and receiver inputs. The
ADM3491E also features separate enable inputs for the
driver and receiver.
The devices have a 12 kΩ receiver input impedance,
which allows up to 32 transceivers on a bus. Because only
one driver should be enabled at any time, the output of a
disabled or powered-down driver is tristated to avoid
overloading the bus.
