Intersil Expands RS-485/RS-422 Family with Three New Transceivers that Offer Reduced EMI and High Data Integrity to Enable Extended Long-run Applications
MILPITAS, CA, August 6, 2003 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today announced the addition of three new members to the RS-485/RS-422 family of high-performance data transceivers, the ISL8483, ISL8488 and ISL8489. These new transceivers operate from a wider supply tolerance than competing products and all pins have greater than 7-kV ESD protection for increased reliability. Slew rate limiting for a 250-kbps data rate minimizes electromagnetic interference (EMI) and delivers high data integrity for extended long-run applications.
Typical applications for these new ICs include factory automation, security networks, keyboard/video/mouse (KVM) switching, industrial/process control networks (e.g., Fieldbus), building environmental control systems, HVAC control systems, level translators, and RS-232 extension cords.
The ISL8483, ISL8488 and ISL8489 are specifically targeted for the lower-data-rate and longer-run applications, said Mamoon Rashid, Director of Marketing for Intersils Analog Solutions Products. These new ICs offer reduced EMI and improved data integrity making them a desirable alternative to, and pin-for-pin replacement for, other products operating in this space.
The ISL8483, ISL8488 and ISL8489 are high-performance drop-in replacements for competing products of similar nomenclature. These new-generation transceivers offer designers an upgrade in performance and signal integrity, especially for long-run applications, and are guaranteed to operate over a +/-10% supply range - thats twice the range offered by most competing ICs.
The ISL8483 is a half-duplex transceiver offering multiplexed receiver (Rx) inputs and driver (Tx) outputs to support Rx and Tx disable functions, all in an 8-lead package. The ISL8488 and ISL8489 operate full duplex with simultaneous transmit and receive in a four-wire network.

All three of Intersils new-generation high-performance RS-485/RS-422 transceivers boast of a mere 160 uA of quiescent current, a 7 V to +12 V common-mode input voltage range and Class 3 ESD protection (>7 kV HBM) on all pins. Both driver output current and thermal limiting protection features are built into each IC. Package options matching competing products include 8- and 14-lead SOIC and PDIP to accommodate drop-in compatibility.
