Product Summary
The MAX3430ESA+ is a fault-protected RS-485 transceiver which features ±80V protection from overvoltage signal faults on communication bus lines. Each device contains one driver and one receiver, and the output pins can withstand faults, with respect to ground, of up to ±80V. Even if the faults occur when the transceiver is active, shut down, or powered off, the device will not be damaged. The MAX3430ESA+ operates from a 3.3V supply and features a slew-rate-limited driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing errorfree data transmission at data rates up to 250kbps. Applications include RS-422/RS-485 Communications, Lighting Systems, Industrial-Control Local Area Networks, Profibus Applications and Multimaster RS-485 Networks.
