ADM2490EBRWZ: High Speed ESD Protected Full-Duplex iCoupler(R) Isolated RS-485 Transceiver

The ADM2490E is an isolated data transceiver with ±8 kV ESD protection that is suitable for high speed, full-duplex communi-cation on multipoint transmission lines. It is designed for balanced transmission lines and complies with ANSI TIA/EIA-485-A-1998 and ISO 8482: 1987(E). The device employs Analog Devices, Inc., iCoupler(R) technology to combine a 2-channel isolator, a three-state differential line driver, and a differential input receiver into a single package.

The differential transmitter outputs and receiver inputs feature electrostatic discharge circuitry that provides protection to ±8 kV using the human body model (HBM). The logic side of the device can be powered with either a 5 V or a 3 V supply, whereas the bus side requires an isolated 5 V supply.

The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where bus contention could cause excessive power dissipation.

The ADM2490E is available in a wide body, 16-lead SOIC package and operates over the -40°C to +105°C temperature range.
