ISL43485 3.3V Half Duplex 30Mbps RS-485/RS-422 Transceiver

Posted on Feb 6, 2014

The Intersil 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 Intersil transceiver is specified for 10% tolerance supplies (3V to 3. 6V). Receiver (Rx) inputs feature a `fail-safe if open` design, which ensures a logic h

igh output if Rx inputs are floating, and the ISL43485 presents a "single unit load" to the RS-485 bus, which allows up to 32 transceivers on the network. Driver (Tx) outputs are short circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive.
