Intersil ISL3178AE
ISL3178AE is ±15kV IEC61000 ESD protected, 3.3V-powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. This device has very low bus currents (+125µA/-100µA), which presents a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters.DATASHEETNOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at ISL3178AE 1-888-INTERSIL or FN6887 ±15kV ESD Protected, 3.3V, Full Fail-Safe, Low Power, High Speed or Slew Rate Rev 3.00 Limited, RS-485/RS-422 Transceivers October 30, 2014 The Intersil For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required.
