Renesas Electronics Corporation Interface - Interface - Drivers, Receivers, Transceivers - ISL81487LIBZ-T ISL81487LIBZ-T

The ISL81487LIBZ-T is a half-duplex RS-485/RS-422 transceiver designed for low power and high-speed communication. It operates from a single +5V supply with a tolerance of 10% (4.5V to 5.5V) and features ±15kV ESD protection on its I/O pins, making it suitable for robust applications. This device presents a fractional unit load, allowing up to 256 transceivers on the bus, which is beneficial for high node count networks such as automated utility meter reading systems and industrial control networks. The ISL81487LIBZ-T supports data rates up to 5Mbps, with a slew rate limited version available for reduced electromagnetic interference (EMI) and minimized reflections in multidrop applications. It includes a fail-safe design that ensures a logic high output when the receiver inputs are floating. The device also features short-circuit protection and thermal shutdown capabilities to prevent damage from excessive power dissipation. The package is an 8-lead SOIC, and it is RoHS compliant.
