Description

The ADM2490E is an isolated data transceiver with ?8 kV ESD protection that is suitable for high speed, full-duplex communication 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? 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.Applications Isolated RS-485/RS-422 Interfaces Industrial Field Networks INTERBUS Multipoint Data Transmission Systems
