Product Summary

The MAX3483CSA is a 3.3V, low-power transceiver for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX3483CSA features slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission at data rates up to 250kbps. Applications include Low-Power RS-485/RS-422 Transceivers, Telecommunications, Transceivers for EMI-Sensitive Applications and Industrial-Control Local Area Networks.
