The Intersil ISL43210 device is a precision, bidirectional, single SPDT analog switch designed to operate from a single +2.7V to +12V supply. Targeted applications include batterypowered equipment that benefit from the devices’ low powerconsumption (5μW), low leakage currents (3nA max), and fastswitching speeds (tON = 28ns, tOFF = 20ns). Cell phones, forexample, often face ASIC functionality limitations. Thenumber of analog input or GPIO pins may be limited anddigital geometries are not well suited to analog switchperformance. This device may be used to “mux-in” additionalfunctionality while reducing ASIC design risk. It’s smallpackage alleviates board space limitations, making it an idealsolution.The ISL43210 is a single committed SPDT, which is perfect for use in 2-to-1 multiplexer applications.
