DATASHEET Low-Voltage, Single Supply, Dual SPST Analog Switches ISL43120, ISL43121, ISL43122 Features The Intersil ISL43120, ISL43121 and ISL43122 devices are Fully specified at 12V, 5V, and 3.3V supplies for 10% precision, bidirectional, dual analog SPST switches designed to tolerances operate from a single +2.7V to +12V supply. Targeted ON-resistance (r ) . 19 ON applications include battery powered equipment that benefit r matching between channels . <1 ON from the devices low power consumption (5W), low leakage currents (100pA max) and fast switching speeds (t = 28ns, Low charge injection 5pC (Max) ON t = 20ns). Cell phones, for example, often face ASIC OFF Single supply operation +2.7V to +12V functionality limitations. The number of analog input or GPIO Low power consumption (P ) .<5W pins may be limited and digital geometries are not well suited to D analog switch performance. This family of parts may be used to Low leakage current . 10nA mux-in additional functionality while reducing ASIC design Fast switching action risk. Some of the smallest packages are available, alleviating -t 28ns ON board space limitations and making Intersils newest line of -t . 20ns OFF low-voltage switches an ideal solution. Guaranteed break-before-make (ISL43122 only) The ISL43120, ISL43121, ISL43122 are dual single-pole/single-throw (SPST) devices. The ISL43120 has Minimum 2000V ESD protection per method 3015.7 two normally open (NO) switches the ISL43121 has two TTL, CMOS compatible normally closed (NC) switches the ISL43122 has one NO and Available in SOT-23 packaging one NC switch and can be used as an SPDT.
