Data Sheet July 2003
Low-Voltage, Single and Dual Supply, Quad SPST, Analog Switches
The Intersil ISL84521, ISL84523, ISL84523 devices are CMOS, precision, quad analog switches designed to operate from a single +2V to +12V supply or from a Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (<1µW), low leakage currents (1nA max), and fast switching speeds (t
ON
= 45ns, t
= 15ns). A12 maximum RON flatness
OFF
ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 4Ω.
The ISL84521, ISL84522, ISL84523 are quad single-pole/ single-throw (SPST) devices. The ISL84521 has four normally closed (NC) switches; the ISL84522 has four normally open (NO) switches; the ISL84523 has two NO and two NC switches and can be used as a dual SPDT, or a dual 2:1 multiplexer.
Table summarizes the performance of this family. For higher performance, pin compatible versions and 3mm x 3mm Quad No-Lead Flatpack (QFN) package see the ISL43140, ISL43142 data sheet.
