Product Summary

The max1483csa is a low-power transceiver for RS-485 and RS-422 communication. The device features slew-rate-limited drivers that minimize EMI and reduces reflections caused by improperly terminated cables. Data rates are guaranteed up to 250kbps. The max1483csa draws only 20μA of supply current. Additionally, it has a low-current shutdown mode that consumes only 0.1μA. Both parts operate from a single +5V supply. The applications of the max1483csa include Low-Power RS-485/RS-422 Networks, Transceivers for EMI-Sensitive Applications, Industrial-Control Local Area Networks, Large 256-Node LANs.
