Description

The MAX489MJD is a low-power, dual-channel, bidirectional RS-485/RS-422 transceiver designed for reliable data communication in industrial and commercial applications. Operable over a wide voltage range of 3.0V to 5.5V, it supports data rates up to 20 Mbps while providing robust signal integrity. The device features a fail-safe design that ensures a high logic level output when no active driver is present, thus preventing communication errors.
Its integrated thermal shutdown protection and low quiescent current make the MAX489MJD suitable for battery-powered applications. The transceiver is housed in a compact 8-pin SOIC package, enabling easy integration into space-constrained designs. With its ability to drive up to 32 transceivers on a single bus and common-mode range extending to ±12V, it provides versatility for various wiring configurations. Overall, the MAX489MJD is ideal for applications requiring reliable long-distance data transmission in noisy environments.
