DATASHEET ISL43120, ISL43121, ISL43122 FN6033 Rev 7.00 Low-Voltage, Single Supply, Dual SPST Analog Switches Aug 17, 2015 The Intersil ISL43120, ISL43121 and ISL43122 devices are Features precision, bidirectional, dual analog SPST switches designed to Fully specified at 12V, 5V, and 3.3V supplies for 10% operate from a single +2.7V to +12V supply. Targeted tolerances applications include battery powered equipment that benefit from the devices low power consumption (5W), low leakage ON-resistance (r ) . 19 ON currents (100pA max) and fast switching speeds (t = 28ns, ON r matching between channels . <1 ON t = 20ns). Cell phones, for example, often face ASIC OFF Low charge injection 5pC (Max) functionality limitations. The number of analog input or GPIO pins may be limited and digital geometries are not well suited to Single supply operation +2.7V to +12V analog switch performance. This family of parts may be used to Low power consumption (P ) .<5W D mux-in additional functionality while reducing ASIC design risk. Some of the smallest packages are available, alleviating Low leakage current . 10nA board space limitations and making Intersils newest line of Fast switching action low-voltage switches an ideal solution. -t 28ns ON The ISL43120, ISL43121, ISL43122 are dual -t . 20ns OFF single-pole/single-throw (SPST) devices. The ISL43120 has Guaranteed break-before-make (ISL43122 only) two normally open (NO) switches the ISL43121 has two Minimum 2000V ESD protection per method 3015.7 normally closed (NC) switches the ISL43122 has one NO and one NC switch and can be used as an SPDT.
