ISL83485

DATASHEET ISL83483, ISL83485, ISL83488, ISL83490, ISL83491 3.3V, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers FN6052 Rev 4.00 Jul 27, 2018 These Renesas RS-485/RS-422 devices are BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Unlike competitive devices, this Renesas family is specified for 10% tolerance supplies (3V to 3.6V). The ISL83483 and ISL83488 use 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 10Mbps are achievable by using the ISL83485, ISL83490, or ISL83491, which feature higher slew rates. Logic inputs (for example, DI and DE) accept signals in excess of 5.5V, making them compatible with 5V logic families. Receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high output if Rx inputs are floating. All...
