8 5V, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers The Intersil RS-485/RS-422 devices are BiCMOS 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication.
Unlike competitive devices, this Intersil family is specified for 10% tolerance supplies (4.
5V to 5.
5V).
The ISL8483, ISL8488, and ISL8489 utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications.
Data rates up to 5Mbps are achievable by using the ISL8485, ISL8490, or ISL8491, which feature higher slew rates.
All devices present a “single unit load” to the RS-485 bus, which allows up to 32 transceivers on the network.
Receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high Rx output if Rx inputs are floating.
