GENERAL DESCRIPTION
The ADM483E is a 5 V, low power data transceiver with ±15 kV
ESD protection suitable for half-duplex communication on
multipoint bus transmission lines. The ADM483E is designed
for balanced data transmission and complies with TIA/EIA
Standards RS-485 and RS-422, which allow up to 32 transceivers
on a bus.
The ADM483E has a low current shutdown mode in which it
consumes only 0.1 μA.
Because only one driver is enabled at any time, the output of a
disabled or power-down driver is three-stated to avoid
overloading the bus.

Drivers are short-circuit current-limited and are protected
against excessive power dissipation by thermal shutdown
circuitry that places their outputs into a high impedance state.
The receiver input has a fail-safe feature that guarantees a logic
high output if the input is open circuit.
The ADM483E is fully specified over the industrial temperature
ranges and is available in 8-lead SOIC_N packages.
