The Intersil RS-485/RS-422 devices are BiCMOS 5Vpowered, single transceivers that meet both the RS-485 andRS-422 standards for balanced communication. Unlikecompetitive devices, this Intersil family is specified for 10%tolerance supplies (4.5V to 5.5V). The ISL8483, ISL8488, and ISL8489 utilize slew rate limiteddrivers which reduce EMI, and minimize reflections fromimproperly terminated transmission lines, or unterminatedstubs in multidrop and multipoint applications.Data rates up to 5Mbps are achievable by using theISL8485, ISL8490, or ISL8491, which feature higher slewrates.
