These Intersil RS-485, RS-422 devices are ESD protected, BiCMOS 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive devices, this Intersil family is specified for 10% tolerance supplies (4.5V to 5.5V).
The ISL8483E utilizes slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or un-terminated stubs in multidrop and multipoint applications.
