Product Summary

The MAX485ESA is designed as one kind of ±15kV ESD-protected, slew-rate-limited, low-power, RS-485/RS-422 transceiver device that can be used in wide range of applications such as (1)low-power RS-485 transceivers; (2)low-power RS-422 transceivers; (3)Level translators; (4)transceivers for EMI-sensitive applications; (5)industrial-control local area networks. Also this device features reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables.
