Description
The ADM2481BRWZ is a differential bus transceiver digital isolator that enables bidirectional data communication on a balanced multipoint bus transmission line. It is compliant with the ISO 8482:1987(E) and ANSI EIA/TIA-485-A standards. The component integrates a 3-channel isolator, a differential input receiver, and a three-state differential line driver, all in one package. The device's logic side is powered by either 5V or 3V; on the other hand, the bus side is powered with one 5V supply exclusively. The ADM2481BRWZ uses iCoupler® technology that is designed by Analog Devices, Inc., a technology that guarantees galvanic isolation.

Comparison
Advantages- High common-mode transient immunity of more than 25 kV/μs
- True fail-safe receiver inputs ensure that the outputs are in a known state when the driver is disabled or the bus is idle
- Chatter-free power-up/power-down protection that enables part stability and prevents spurious switching that can occur during power-up or power-down sequences
- Transient voltage suppression technology protects the input signal from overvoltage transients
- Suitable for low power operation
Disadvantages- VDE certificates of conformity DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 might not be acceptable in all countries or jurisdictions
