ISL84544

Low-Voltage, Single Supply, Dual SPST, SPDT Analog Switches

Product Status: 量産中(*)

OVERVIEW

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 (5µW), 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 single pole/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 applications.
