GENERAL DESCRIPTION
The ADM483E is a robust, low power differential line transceiver suitable for communication on multipoint bus transmission lines. Internal protection against electrostatic discharge
(ESD), electrical fast transient (EFT) and electromagnetic
immunity (EMI) allows operation in electrically harsh environments. ESD protection on the I-O lines meets ? 15 kV when
tested using the Human Body Model. EFT protection meets
?2 kV in accordance with IEC1000-4-4, while EMI immunity is
in excess of 10 V/m meeting IEC1000-4-3.
