ADM2491E Datasheet PDF (Half-/Full-Duplex iCoupler Isolated RS-485 Transceiver)

ADM2491E - Half-/Full-Duplex iCoupler Isolated RS-485 Transceiver

Description

The ADM2491E is an isolated data transceiver with ±8 kV ESD protection and is suitable for high speed, half- or full-duplex communication on multipoint transmission lines.

For halfduplex operation, the transmitter outputs and the receiver inputs share the same transmission line.

Features

Isolated, RS-485/RS-422 transceiver, configurable as half- or full-duplex ±8 kV ESD protection on RS-485 input/output pins 16 Mbps data rate Complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E) Suitable for 5 V or 3.3 V operation (VDD1) High common-mode transient immunity: >25 kV/μs Receiver has open-circuit, fail-safe design 32 nodes on the bus Thermal shutdown protection Safety and regulatory approvals UL recognition: 5000 V rms isolation voltage for 1 minute, per UL 1577 VDE certifi.
