The RS422/RS485 transceiver from Renesas, part number 84AC7063, operates within a temperature range of -40 to 85 degrees Celsius. It features ±15kV ESD protection on the RS-485 I/O pins and over 7kV on all other pins, ensuring robust performance in electrically noisy environments. This device supports a fractional unit load, allowing up to 256 devices on the bus, making it suitable for high node count networks. It operates from a single +5V supply with a tolerance of 10%, and offers low quiescent supply current, with a maximum of 145µA for certain versions. The transceiver supports data rates of up to 5Mbps for high-speed applications, while slew rate limited versions can achieve up to 250kbps, reducing electromagnetic interference. It includes features such as thermal shutdown and current limiting for driver overload protection, and is available in both SOIC and PDIP packages, compliant with RoHS standards. This transceiver is ideal for applications in factory automation, security networks, and industrial control systems.
These Intersil RS-485/RS-422 devices are ESD protected, fractional unit load (UL), BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output/ receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive devices, this Intersil family is specified for 10% tolerance supplies (4.5V to 5.5V).brbr All devices present a 1/8 "unit load" to the RS-485 bus, which allows up to 256 transceivers on the network for large node count systems (e.g., process automation, remote meter reading systems). In a remote utility meter reading system, individual (apartments for example) utility meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required to network all the meters. Data for all meters is then read out from the concentrator via a single access port, or a wireless link.brbr Slew rate limited drivers on the ISL8487E and ISL81487L reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Data rates up to 250kbps are achievable with these devices.brbr Data rates up to 5Mbps are achievable by using the ISL81487E, which features higher slew rates.brbr Receiver (Rx) inputs feature a "fail-safe if open" design, which ensures a logic high Rx output if Rx inputs are floating.brbr 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.brbr These half duplex devices multiplex the Rx inputs and Tx outputs to allow transceivers with Rx and Tx disable functions in 8 lead packages.
