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, has announced two new LINEARLINK full-duplex RS-485/422 transceivers, the ISL ISL - Interface Specification Language.

These new transceivers are drop-in upgrades from competing parts of similar nomenclature and offer full 15 kV ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine.

"The ISL8489E and ISL8491E provide industry leading speed, reach, data integrity, reliability and flexibility that designers of copper pair bus networks need to meet today's high-performance demands," said Michael Althar, Vice President of Intersil's Analog Solutions Product Group. "Intersil continues to expand the LINEARLINK interface products portfolio with the addition of these new high-performance full-duplex RS-485/422 transceivers."
These new RS-485/422 transceivers are full duplex, configured for four-wire RS-485 networks, which allows simultaneous transmit and receive capability, or for RS-422 networks where only one driver is allowed on a 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 logic pins, which greatly improves survivability sur·viv·a·ble

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. Exceeding the tolerance of many competing parts, the ICs operate with a +/-10 percent tolerance from a 5-V supply (4.5 to 5.5 V range).
Both the ISL8489E and ISL8491E are single-unit load devices that allow up to 32 nodes per bus and offer a choice of speed. The ISL8489E is a 250-kbps data rate device that has slew rate limited drivers intended for long-run applications. The slew rate limiting reduces EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. and minimizes reflections from improperly terminated transmission lines or non-terminated stubs stubs

The ISL8491E is a 10-Mbps device designed for high-speed short runs.
