ADM3491EARZ General Description
The ADM3483E / ADM3486E / ADM3488E / ADM3490E / ADM3491E are 3.3 V low power data transceivers with ±15 kV ESD protection suitable for full andhalf-duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with TIA/EIA standards RS-485 and RS-422. The ADM3483E / ADM3486E is a half-duplex transceiver that shares differential lines and has 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 enable inputs for the driver and receiver.
Features
