ISL5120 ISL5120, ISL5121 ISL5121, ISL5122 ISL5122, ISL5123 ISL5123 ® Data Sheet April 2002 Low-Voltage, Single Supply, Dual SPST, SPDT Analog Switches The Intersil ISL5120 ISL5120­ISL5123 ISL5123 devices are precision, bidirectional, dual analog switches designed to operate from a single +2.7V to +12V supply. Targeted applications include battery powered equipment that benefit from the devices' low power consumption (5µW), low leakage currents (100pA max), and fast switching speeds (tON = 28ns, tOFF = 20ns). Cell phones, for example, often face ASIC functionality limitations. The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch performance. This family of parts may be used to "muxin" additional functionality while reducing ASIC design risk. Some of the smallest packages are available, alleviating board space limitations, and making Intersil's newest line of low-voltage switches an ideal solution. The ISL5120/ISL5121/ISL5122 ISL5120/ISL5121/ISL5122 are dual single-pole/singlethrow (SPST) devices. The ISL5120 ISL5120 has two normally open (NO) switches; the ISL5121 ISL5121 has two normally closed (NC) switches; the ISL5122 ISL5122 has one NO and one NC switch and can be used as an SPDT. The ISL5123 ISL5123 is a committed SPDT, which is perfect for use in 2-to-1 multiplexer applications. TABLE 1.
