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 half-duplex operation, the transmitter outputs and the receiver inputs share the same transmission line. Transmitter output Pin Y is linked externally to receiver input Pin A, and transmitter output Pin Z to receiver input Pin B.
The ADM2491E is designed for balanced transmission lines and complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E). The device employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a threestate 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 3.3 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 ADM2491E is available in a wide body, 16-lead SOIC package and operates over the −40°C to +85°C temperature range.
