August 19, 2015 Low-Voltage, Single Supply, Dual SPST, SPDT Analog Switches
The Intersil ISL84541–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 (5пЃ­W), 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, and making Intersil’s newest line of low-voltage
switches an ideal solution.
The ISL84541/ISL84542/ISL84543 are dual singlepole/single-throw (SPST) devices. The ISL84541 has two
normally open (NO) switches; the ISL84542 has two normally
closed (NC) switches; the ISL84543 has one NO and one NC
switch and can be used as an SPDT. The ISL84544 is a
committed SPDT, which is perfect for use in 2-to-1 multiplexer …
