Intersil Extends Analog Switch Line with new Low-Voltage High-Performance Switches

-- New analog switches offer high performance and enhanced device characterization

IRVINE, CA, November 2, 2001 – 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 ISL84541, ISL84542, ISL84543 and ISL84544 high-performance switches. Targeted applications include portable battery-powered equipment in which space and power consumption are concerns. Thorough documentation aids design-ins.

These new low-voltage single-supply switches are available as dual single-pole single-throw (SPST) or single-pole double-throw (SPDT) in the small SOT-23 package and offer characterization improvements over the industry parts they are designed to replace.

The ISL84541, ISL84542, ISL84543 and ISL84544 are pin compatible with the MAX4541-4, MAX323-5, DG9262-3, and DG9461 devices. By maintaining a second supplier in high-volume applications, customers reduce their risk of part shortages when industry demand strains supplier capacity.

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

Technical Features
The ISL84541/2/3/4 devices are precision dual analog switches that operate from a single +2.7V to +12V supply. The ISL84541, ISL84542 and ISL84543 are offered in the 8-lead SOT-23 package, and the ISL84544 is offered in the 6-lead SOT-23 package. These packages meet the needs of high-growth portable appliance markets. Other packages are also available.

The ISL84541, ISL84542 and ISL84543 offer dual SPST configurations, and the ISL84544 offers a SPDT configuration. The ISL84541 features two normally open (NO) switches, and the ISL84542 features two normally closed (NC) switches. The ISL84543 features one NO and one NC switch offering optional SPDT functionality, while the ISL84544 is a SPDT switch that can easily be utilized as a high performance 2-to-1 multiplexer.

Targeted applications include portable battery-powered equipment in which space and power consumption are concerns. Extremely low power consumption (<5 µW) extends battery life, low leakage currents (100 pA max) lengthen hold times in sample-and-hold-circuits, and fast switching speeds (t_ON = 35 ns typ, t_OFF = 25 ns typ) reduce propagation delay in timing sensitive applications. The parts offer minimal charge injection (5 pC max) to maximize signal integrity, and they come in some of the smallest packages alleviating board space limitations. This combination of features makes Intersil’s newest switches an ideal solution for low-power space-constrained applications.
