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). Data rates up to 30Mbps are achievable by using this transceiver, which features higher slew rates. Logic inputs (e. g. , 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, 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.
