ADM1485JR Description

Short technical summary and product information.

The ADM1485JR is a differential line transceiver designed for high-speed bidirectional data communication on multipoint bus transmission lines. It complies with EIA RS-485 and RS-422 standards.

 

Key electrical specifications include a data rate of 30 Mbps, supply voltage range of 4.75V to 5.25V, and bus common-mode range of -7V to +12V. The driver propagation delay is 10 ns and receiver propagation delay is 15 ns (datasheet). It features thermal shutdown and ESD protection.

 

The device supports up to 32 transceivers on a single bus. Fail-safe circuitry ensures a logic high output on floating inputs. The driver and receiver can be independently enabled.

 

The ADM1485JR is surface mounted in an 8-SOIC package (0.154", 3.90mm width). It operates over commercial temperature range.
