Exar Adds 5V RS-485/RS-422 Half-Duplex Transceiver
Ideal for Industrial and Remote Data Collection Applications
FREMONT, Calif., Jan. 15 / / -- Exar Corporation (NASDAQ:EXAR) released a new highly integrated 5V RS-485/RS-422 half duplex transceiver -- the SP4082E -- which complements Exar's SP308x family of transceivers. The SP4082E, when added to Exar's full serial transceiver product portfolio, gives customers a wide variety of options for their designs. The SP4082E targets remote E-metering monitoring, building automation, HVAC controls, security camera systems and applications on long, or un-terminated transmission lines, amongst others.
"The SP4082E offers robust features and functions appropriate for applications that require optimal system performance vs. cost," said Hensen Wong, technical marketing manager, Interface Products. "Furthermore, the SP4082E was designed for harsh environments where device reliability and sustained performance is critical."
Key Product Features
The SP4082E is designed for reliable, bidirectional communication on multipoint bus transmission lines and contains one differential driver and one differential receiver. It supports the entire common-mode voltage range from -7V to +12V. Receivers are specially designed to fail-safe to a logic high output state if the inputs are left un-driven or shorted. In addition, all receivers have exceptionally high input impedance, which places only 1/8th the standard load on a shared bus. All RS-485 bus-pins are protected against severe ESD events up to +/-15kV (Human Body Model). Drivers are protected from excess current flow caused by bus contention or output short-circuits by both an internal current limit and a thermal-overload shutdown. Up to 256 transceivers may coexist while preserving full signal margin. The device is compliant with TIA/EIA-485 and TIA/EIA-422 standards.
The device operates from a single 5.0V power supply and draws negligible quiescent power. The device can independently enable and disable the driver and receiver and enter a low power shutdown mode if both driver and receiver are disabled. All outputs maintain high impedance in shutdown or when powered-off.
Interface Products
Exar has one of the broadest portfolios of high-performance interface solutions including UARTs, serial transceivers -- RS-232, RS-485, and multi-protocol -- and integrated UART/transceiver combinations. For chip-to-chip or system-to-system connections, Exar's single and multi-channel interface ICs provides immediate competitive advantages to designers: low power, reduction in board space requirements, increased bandwidth capacity, and enhanced product features. Interface devices are found practically everywhere including point-of-sale (POS) terminals, digital televisions, industrial automation equipment, handheld devices, and networking environments.
Prices, Packages, Availability and Additional Information
Samples of the SP4082E are available now in an 8-pin SOIC package supporting the -40 degrees C to +85 degrees C temperature range. Lead-free and RoHS compliant packages are available. In 1k piece quantities the SP4082E is $0.49.
