ISL43L120, ISL43L121, ISL43L122 Data Sheet June 23, 2006 FN6091.2 Ultra Low ON-Resistance, Single Supply, Features Dual SPST Analog Switches Low ON Resistance (R ) ON The Intersil ISL43L120, ISL43L121, ISL43L122 devices are - V+ = 3.0V 0.16 low ON-resistance, low voltage, bidirectional, precision, dual - V+ = 1.8V . 0.26 single-pole/single-throw (SPST) analog switches designed Matching Between Channels 0.005 R ON to operate from a single +1.65V to +3.6V supply. Targeted applications include battery powered equipment that benefit R Flatness Over Signal Range 0.008 ON from low R (0.16), low power consumption (0.12W) ON Single Supply Operation +1.65V to +3.6V and fast switching speeds (t = 13ns, t = 13ns). ON OFF Low Power Consumption (P ) . <0.12W D Cell phones, for example, often face ASIC functionality Fast Switching Action (V+ = 3.0V) limitations. The number of analog input or GPIO pins may be 13ns -t limited and digital geometries are not well suited to analog ON switch performance. This family of parts may be used to -t . 13ns OFF switch in additional functionality while reducing ASIC design ESD HBM Rating >8kV risk. The ISL43L12X are offered in an 8 Ld MSOP package, 1.8V Logic Compatible (+3V Supply) alleviating board space limitations. Available in 8-Ld thin DFN and 8-Ld MSOP Packages The ISL43L120, ISL43L121, ISL43L122 are dual single- pole/single-throw (SPST) devices. The ISL43L120 has two Pb-Free Plus Anneal Available (RoHS Compliant) normally open (NO) switches the ISL43L121 has two normally closed (NC) switches the ISL43L122 has one Applications normally open (NO) and one normally closed (NC) switch Battery Powered, Handheld, and Portable Equipment and can be used as an SPDT. - Cellular/Mobile Phones Table 1 summarizes the performance of this family. - Pagers - Laptops, Notebooks, Palmtops TABLE 1.
