It supports data rates up to 2.5 Mbps over balanced differential lines, making it suitable for industrial multi-point networks and long-haul communication links where common-mode noise rejection is critical. The full-duplex architecture allows simultaneous transmit and receive on separate twisted pairs, halving the protocol overhead compared to half-duplex alternatives. ## Supply voltage and temperature grade Surface-mount assembly in the 14-SOIC (150-mil body width) footprint matches standard SOIC-14 land patterns. The tape-and-reel packaging supports automated pick-and-place for volume production.","metaTitle":"MAX491EESD+T RS-485/RS-422 Transceiver, 2.5 Mbps, 14-SOIC","metaDescription":"MAX491EESD+T full-duplex RS-485/RS-422 transceiver from Analog Devices. 2.5 Mbps data rate, 1/1 driver/receiver, 14-SOIC.
