ISL43485 - RS-485/RS-422 Transceiver

Features

  • higher slew rates. Logic inputs (for example, DI and DE) accept signals in excess of 5.5V, making them compatible with 5V logic families. The receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high output if Rx inputs are floating. The ISL43485 presents a “single unit load” to the RS-485 bus, which allows up to 32 transceivers on the network. The driver (Tx) outputs are short-circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-c.

DATASHEET ISL43485 3.3V, Low Power, 30Mbps, RS-485/RS-422 Transceiver FN6071 Rev.2.00 Sep 19, 2018 The Renesas ISL43485 is a high speed BiCMOS 3.3V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced communication. Unlike some competitive devices, this transceiver is specified for 10% tolerance supplies (3V to 3.6V). Data rates up to 30Mbps are achievable by using this transceiver, which features higher slew rates. Logic inputs (for example, DI and DE) accept signals in excess of 5.5V, making them compatible with 5V logic families. The receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high output if Rx inputs are floating.
