MAX3491CSD General Description
The MAX3491CSD+ is a quad, low-voltage, 2.5V to 5.5V, RS-232/RS-485/RS-422 multiprotocol transceiver. It integrates four transceivers that support RS-232, RS-485, and RS-422 protocols, making it versatile for various communication applications. Operating from a single 2.5V to 5.5V supply, it consumes low power, enhancing efficiency in portable and low-power devices. The device offers high data rates up to 460kbps, suitable for fast communication needs. Its integrated protection features guard against overvoltage, ESD events, and short-circuit conditions, ensuring robustness in harsh environments. The MAX3491CSD+ also incorporates slew-rate-limited drivers to minimize EMI and reduce reflections from improperly terminated transmission lines. With its small footprint and compatibility with multiple protocols, the MAX3491CSD+ is an efficient solution for industrial automation, instrumentation, and communication equipment requiring versatile serial communication interfaces
