Intersil Continues Expansion of MightyMUX™ Switch Line with Three New Low-Voltage Quad Analog Switches
-- High performance for battery-operated portable devices and high-precision equipment~-- New switches operate from single or dual supplies and offer low leakage and fast switching
IRVINE, CA, October 10, 2002 Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high performance analog and wireless networking solutions, today announced three new additions to their rapidly growing MightyMUX high-performance analog switch line the ISL84521, ISL84522 and ISL84523. These new quad switches follow closely on the heels of seven products already released this quarter and add further flexibility for designers of low-voltage applications in portable equipment and high precision instrumentation.
Targeted applications include portable battery-powered equipment in which space and power consumption are concerns and high-precision equipment used for medical, communications, and testing. Low leakage currents (10 nA max) lengthen hold times in sample-and-hold-circuits and fast switching speeds (tON = 45 ns, tOFF = 15 ns) reduce propagation delays in timing sensitive applications. These switches offer minimal charge injection of only 5 pC (max) to maximize signal integrity. The tiny 3 X 3-mm QFN package requires very little board space. This combination of features makes Intersils newest switches an ideal solution for low-power space-constrained applications.
Each of these new ICs contain four single-pole single-throw (SPST) configured switches and operate from a single 2-V to 12-V supply or a dual ±2-V to ±6-V supply. The ISL84521 has all normally closed (NC) switches, while the ISL84522 features all normally open (NO) switches. The ISL84523 has two normally open and two normally closed switches, which can be configured as a double-pole double-throw (DPDT) switch or as dual 2-to-1 multiplexers. All devices can be used as switches or multiplexers.
Each of these new Intersil MightyMux switches is available in 16-lead SOIC, 16-lead TSSOP and 16-pad QFN packages. The ISL84521, ISL84522 and ISL84523 are drop-in replacements for the Maxim MAX4521, MAX4522 and MAX4523 respectively. By maintaining a second supplier in high-volume applications, customers reduce their risk of part shortages when industry demand strains supplier capacity.
