The ISL317XE are ±15kV IEC61000 ESD Protected, 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents, allowing up to 256 transceivers on the network without violating the RS-485 specification’s maximum limit. The receivers feature a Full Fail-Safe design and the transceivers have hot plug circuitry to ensure stable operation. Slew rate limited versions reduce EMI and minimize reflections from improperly terminated transmission lines. The ISL3170E through ISL3175E also include receiver input filtering to enhance noise immunity in the presence of slow input signals.
