Product Summary

The MAX485ECSA is a RS-485/RS-422 Transceiver. The MAX485ECSA is low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX485ECSA feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX485ECSA is not limited, allowing them to transmit up to 2.5Mbps. The applications of the MAX485ECSA include Low-Power RS-485 Transceivers, Low-Power RS-422 Transceivers, Level Translators, Transceivers for EMI-Sensitive Applications and Industrial-Control Local Area Networks.
