ISL8487, ISL81483, ISL81487 1/8 Unit Load, 5V, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers FN6050 Rev 8.00 March 14, 2016 These Intersil RS-485/RS-422 devices are “fractional” unit load (UL), Bi CMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced munication. Unlike petitive devices, this Intersil family is specified for 10% tolerance supplies (4.5V to 5.5V). The ISL81483 and ISL81487 present a 1/8 unit load to the RS-485 bus, which allows up to 256 transceivers on the network for large node count systems (e.g., process automation, remote meter reading systems). The 1/4 UL ISL8487 allows up to 128 transceivers on the bus. In a remote utility meter reading system, individual (apartments for example) utility meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required to network all the meters.
