The Infineon ISL81487 is a BiCMOS, 5V powered single transceiver that meets both RS-485 and RS-422 standards for balanced communication. It is specified for 10% tolerance supplies, operating from 4.5V to 5.5V. The ISL81487 presents a 1/8 unit load to the RS-485 bus, enabling up to 256 transceivers on the network for large node count systems, such as process automation and remote meter reading.
This high-speed version achieves data rates up to 5Mbps. The receiver inputs feature a fail-safe design, ensuring a logic high output if inputs are floating. Driver outputs are protected against short circuits and excessive power dissipation via on-chip thermal shutdown circuitry. These half-duplex devices are available in 8 Ld packages and offer three-state Rx and Tx outputs.
The ISL81487 is a drop-in replacement for Maxim's MAX1487 and National Semiconductor's LMS1487. Its robust design and high node count capability make it suitable for industrial and commercial communication systems requiring reliable data transmission over long distances.
