Intersil launches world's fastest 5 V fractional-unit load full duplex RS-485/422 transceiver with 15 kV ESD protection.Intersil Corporation (Nasdaq:ISIL ISIL International Society for Individual Liberty ISIL Interim Support Items List ISIL Intelligence Systems Integration Laboratory (Ft. Huachuca, Arizona; US Army facility for integrating intelligence systems) ), a leader in the design and manufacture of high performance analog solutions, today announced two new LINEARLINK full-duplex RS-485/422 transceivers, the ISL ISL - Interface Specification Language.

E-mail: Bill Janssen <janssen@parc.xerox.com>. 4489E and ISL4491E. The ISL4491E is the world's fastest 5-V, full-duplex, one-eighth fractional-unit load transceiver (TRANSmitter reCEIVER) An electronic device or circuit that transmits and receives analog or digital signals. It comes in many forms; for example, a transponder on a satellite, a network adapter in the computer or the circuits in a cellphone. with 15-kV ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine. See ESL. protection. These new devices boost performance in a wide range of industrial and commercial applications where speed and reach are important. "The ISL4489E and ISL4491E are exceptional RS-485 speed and reach options that designers can select for new balanced twisted pair A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network cabling. The wires are twisted around each other to minimize interference from other twisted pairs in the cable (Alexander Graham Bell invented this and was awarded a patent for it in 1881). networks that contain up to 256 nodes," said Mamoon Rashid, director of Intersil's Analog Solutions Product Group. "These new transceivers provide extended reach, the highest data integrity and full 15-kV ESD protection to increase reliability and survivability sur·viv·a·ble adj. 1.

Both the ISL4489E and the ISL4491E are one-eighth fractional-unit load transceivers that enable up to 256 nodes on the 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 in large networks that span a wide area, such as found in factory automation, process control, environmental control or security applications. The ISL4489E is a 250 kbps slew-rate limited device intended for long networks while the ISL4491E is a 15 Mbps device intended for short-run networks at high data transfer rates. As full-duplex transceivers, the ISL4489E and ISL4491E are configured for four-wire RS-485 networks. Four-wire networks allow simultaneous transmit and receive capability. They may also be used for RS-422 networks where only one driver is allowed on each two-wire bus. The ICs are ESD protected to 15 kV on all transmit (Tx) and receive (Rx) bus pins and up to 7 kV on all other pins, which greatly improves survivability from random static charges during manufacturing and use. Packaged in a 14-lead 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. , the devices are rated for the industrial temperature range of -40 to +85 degrees. |
