Product Summary

The MAX1482EPD is a low-power transceiver for RS-485 and RS-422 communication. It features slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables. Data rates are guaranteed up to 250kbps. Additionally, the MAX1482EPD has a low-current shutdown mode that consumes only 0.1uA. Both parts operate from a single +5V supply. The applications of the MAX1482EPD are Low-Power RS-485/RS-422 Networks, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks, Large 256-Node LANs.
