Description
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 ±2V to ±6V supply. Targeted applications include battery powered equipment that benefit from the devices' low power consumption (1µW), low leakage currents (1nA max), and fast switching speeds (tON = 45ns, tOFF = 15ns). A12Ω maximum RON flatness 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.
