It integrates a three-channel iCoupler digital isolator with an RS-485 transceiver, providing 2.5kV rms galvanic isolation between the logic side and bus side. The half-duplex transceiver supports data rates up to 20Mbps with full failsafe receiver operation. This tube-packaged version is suitable for lower-volume production or prototyping where tape and reel handling is not required.","working_principle":"The ADM2484EBRWZ operates identically to the REEL7 variant. (1) The iCoupler digital isolator transfers DI, DE, and RE logic signals across the 2.5kV rms isolation barrier using on-chip transformer coupling with CMOS encoding\/decoding. (2) The RS-485 transceiver on the bus side converts single-ended logic to differential bus signals for transmission (A\/B pins) and converts received differential signals back to single-ended logic on RO. (3) The driver enable (DE) and receiver enable (RE) control the direction for half-duplex operation, with full failsafe receiver ensuring logic-high output during bus idle, open, or short conditions.","pin_description":"
