E-mail: Bill Janssen <janssen@parc.xerox.com>. 8307xE devices are the latest additions to Intersil's expanding family of transceivers and feature full fail-safe and hot swap To pull out a component from a system and plug in a new one while the main power is still on. Also called "hot plug" and "hot insertion," hot swap is a feature of USB devices, allowing an external drive, network adapter or other peripheral to be plugged in without having to power down the features along with fractional load (up to 256 nodes) and 15kV HBM HBM Human Body Model HBM Human Brain Mapping HBM Hottinger Baldwin Messtechnik GmbH (German company) HBM High Bone Mass HBM Hybrid Bilayer Membrane HBM Humming Bird Medal HBM Her/His Britannic Majesty ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine.

Intersil Corporation (NASDAQ:ISIL), a world leader in the design and manufacture of high performance analog solutions, today announced seven new data transceivers that are BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for differential data communications data communications, application of telecommunications technology to the problem of transmitting data, especially to, from, or between computers. In popular usage, it is said that data communications make it possible for one computer to "talk" with another. . Such devices utilize balanced data-transmission schemes and are robust solutions for transmitting data over long distances and in noisy environments. These devices are ideal for applications in factory automation, security networks, building environmental control systems, industrial process control systems and automated utility meter-reading systems. The ISL8307xE family features enhancements over the current portfolio of Intersil transceivers, covering the range of features associated with the RS-485 protocol. In addition to full fail-safe receivers and hot swap circuitry, the devices provide fractional unit the unit of a fraction; the reciprocal of the denominator; thus, ¼ is the unit of the fraction See also: Unit I/O - Input/Output ) pins and 7kV HBM ESD on all other pins. The ESD protection provides a high degree of reliability in both manufacturing and end-customer applications and eliminates the need for external protection circuitry. Also the devices are packaged in tiny MSOP packages, which are 50 percent smaller that standard SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. packages. "Our new 3.3 volt family complements the 5V family (ISL8308xE) of transceivers we introduced last fall and brings our total transceiver portfolio to well over 100 devices," said Randy Pitts, product marketing manager for Interface products in Intersil's Analog Signal Processing Analog signal processing is any signal processing conducted on analog signals by analog means. "Analog" indicates something that is mathematically represented as a set of continuous values. This differs from "digital" which uses a series of discrete quantities to represent signal. Products Group. "These industry-leading full feature 3.3 volt parts join our expanding family of 5 volt, full duplex (Computers) arranged so that the information may be transmitted in both directions simultaneously; - of communications channels between computers; contrasted with The ISL8307xE receiver (Rx) inputs feature a full fail-safe design, which ensures a logic high Rx output if Rx inputs are floating, shorted or terminated but un-driven. This prevents Rx output chattering for predictable performance during bus faults. Hot swap circuitry is included on all the devices to ensure that the transmitter (Tx) and Rx outputs remain tri-stated during power up. This ensures data isn't disrupted when a node is plugged into an active bus. Three data rate options provide two slew rate-limited options for low data rates (250 kbps and 500 kbps) and a high-speed option for up to 20 Mbps data rates. These devices are one-eighth (fractional) unit load transceivers that enable up to 256 nodes on the RS-485 bus as compared to only 32 nodes for single-unit load devices. The large number of nodes on a single bus saves cost and complexity by eliminating the need for repeaters in large networks (i.e. e-power meters, factory automation, process/environmental control or security systems). Power-up circuitry ensures that the Tx and Rx outputs remain in a high impedance In electronics, high impedance (also known as hi-Z, tri-stated, or floating) is the state of an output terminal which is not currently driven by the circuit. state until the power supply has stabilized. 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, and the Tx outputs automatically re-enable once the IC cools down. These ICs are ESD protected to 15kV (HBM) on all Tx and Rx bus pins and up to 7kV on all logic pins, which greatly improves survivability sur·viv·a·ble adj. 1.

Unlike some competitive devices, Intersil's new RS-485 and RS-422 transceivers are specified for 10 percent tolerance supplies (3.0V to 3.6V).
