The ADM2491EBRWZ 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 is linked to receiver input pin-B. The ADM2491E is designed for balanced transmission lines. The device employs Analog Devices Inc., iCoupler® technology to combine a 3-channel isolator, a 3-state differential line driver and a differential input receiver. The differential transmitter outputs and receiver inputs feature electrostatic discharge circuitry that provides protection to ±8kV using the human body model (HBM). The logic side of the device can be powered with either 5 or 3.3V supply, whereas the bus side requires an isolated 5V supply.
● High common-mode transient immunity - >25kV/µs
● Receiver has open-circuit failsafe design
● 32 Nodes on the bus
● Thermal shutdown protection
