DATASHEET Low Voltage, Single Supply, Dual SPST, SPDT Analog Switches ISL5120, ISL5121, ISL5122, Features Improved (lower r , faster switching), pin compatible ISL5123 ON replacements for ISL84541, ISL84542, ISL84543, The Intersil ISL5120, ISL5121, ISL5122, ISL5123 devices are ISL84544 precision, bidirectional, dual analog switches designed to Fully specified at 3.3V, 5V, and 12V supplies operate from a single +2.7V to +12V supply. Targeted applications include battery powered equipment that benefit ON resistance (r ) . 19 ON from the devices low power consumption (5W), low leakage r matching between channels . 1 ON currents (100pA max), and fast switching speeds (t = 28ns, ON Low charge injection . 5pC (Max) t = 20ns). Cell phones, for example, often face ASIC OFF functionality limitations. The number of analog input or GPIO Single supply operation +2.7V to +12V pins may be limited and digital geometries are not well suited to Low power consumption (P ) <5W D analog switch performance. This family of parts may be used to mux-in additional functionality while reducing ASIC design Low leakage current . 10nA risk. Some of the smallest packages are available, alleviating Fast switching action board space limitations and making Intersils newest line of -t 28ns ON low-voltage switches an ideal solution. -t . 20ns OFF The ISL5120, ISL5121, ISL5122 are dual Guaranteed break-before-make (ISL5122/ISL5123 only) single-pole/single-throw (SPST) devices. The ISL5120 has two Minimum 2000V ESD protection per method 3015.7 normally open (NO) switches the ISL5121 has two normally closed (NC) switches the ISL5122 has one NO and one NC TTL, CMOS compatible switch and can be used as an SPDT. The ISL5123 is a Available in SOT-23 packaging committed SPDT, which is perfect for use in 2-to-1 multiplexer applications. Pb-free (RoHS compliant) TABLE 1.
