Intersil ISL43485IB

ТрансиверRS422, RS48550 Мбит/с

Overview

The Intersil ISL43485IB 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 ISL43485IB 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.
