Intersil Offers Superior Performance Low Voltage Analog Switches

-- Industry's lowest ON resistance and fastest switching times for devices with a maximum 15-V supply

IRVINE, CA, April 29, 2002 – Intersil Corporation (NASDAQ: ISIL), a leading provider of silicon technology for wireless access and communications analog markets, today announced the expansion of their analog switch line with the addition of the ISL5120, ISL5121, ISL5122 and ISL5123 high-performance switches. The broad range of applications includes portable battery-powered equipment in which space and power consumption are concerns. Device design-in is aided by thorough documentation of part performance over the entire specified voltage and temperature ranges.

These high performance switches offer the industry’s lowest on resistance (19 Ù) and fastest switching times (28/20 ns, Ton/Toff) for switches rated in the +15-V maximum range. Competing switches in this range typically have ON resistances of 30 Ù and higher and switching times of 35/25 ns and higher.

The new +2.7 to +12-V (+15 V max) single-supply switches are available as dual single-pole single-throw (SPST) or single-pole double-throw (SPDT) configurations in the SOIC or smaller SOT-23 packages. They are offered in industry standard pin configurations.

High frequency applications also benefit from the new switches’ wide bandwidth, and very high OFF isolation and cross-talk rejection. Signal response is flat even past 300 MHz, consistent over a wide V+ range, and stable for varying analog signal levels. At 1 MHz, OFF isolation is greater than 70 dB in 50 W systems, decreasing approximately 20 dB per decade as frequency increases.

Intersil provides data sheets with enhanced device characterization data for these new switches, which includes complete specification tables at +3.3 V, +5 V and +12 V and specifications measured over the full temperature range. Engineers who need a full range of performance data for new product designs require this comprehensive documentation.
