The ISL84541 and ISL84544 devices are precision, 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 (5W), low leakage currents (100pA max), and fast switching speeds (tON = 35ns, tOFF = 25ns). 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 mux-in additional functionality while reducing ASIC design risk. Some of the smallest packages are available alleviating board space limitations.
The ISL84541 is a dual single-pole/single-throw (SPST) device. The ISL84541 has two normally open (NO) switches. The ISL84544 is a committed SPDT, which is perfect for use in 2-to-1 multiplexer applications.
Table 1 summarizes the performance of this family. For higher performance, pin compatible versions, see the ISL43120 - 22 and ISL43210 datasheet.
