Product Details
Purchasing and Inquiry
describe
The ADM2491E is an isolated data transceiver with ±8 kV ESD protection for high-speed half-duplex or full-duplex communication on multipoint transmission lines. For half-duplex operation, the transmitter output shares the same transmission line as the receiver input. Transmitter output pin Y is externally connected to receiver input pin A, and transmitter output pin Z is externally connected 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) standards. Using Analog Devices' iCoupler® technology, the device integrates a triple-channel isolator, 3-state differential line driver, and differential input receiver on a single chip.
The differential transceiver output and receiver input feature electrostatic discharge circuitry that provides ±8 kV protection to the human body model (HBM). The logic side of the ADM2491E is powered by a 5 V or 3.3 V supply, while the bus side requires an isolated 5 V supply.
The device features current limiting and thermal shutdown to protect against output short circuits and prevent excessive power dissipation due to bus contention.
The ADM2491E is available in a wide body 16-lead SOIC package and operates over the -40°C to +85°C temperature range.
