GENERAL DESCRIPTION ADM483EARZ

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.
