RENESAS ISL5123CBZ

The Intersil ISL5120, ISL5121, ISL5122, 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). This family of parts may be used to “mux-in” 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 are dual single-pole/single-throw (SPST) devices. The ISL5120 has two normally open (NO) switches; the ISL5121 has two normally closed (NC) switches; the ISL5122 has one NO and one NC switch and can be used as an SPDT. The ISL5123 is a committed SPDT, which is perfect for use in 2-to-1 multiplexer applications.
