低电压单和双电源四路SPST模拟开关ISL8391, ISL8392, ISL8393

　　The Intersil ISL8391–ISL8393 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 （2.5nA max）， and fast switching speeds （tON = 60ns， tOFF = 30ns）。 A 4Ω maximum RON flatness ensures signal fidelity， while channel-to-channel mismatch is guaranteed to be less than 2Ω。 The ISL8391， ISL8392， and ISL8393 are quad single-pole/single-throw （SPST） devices. The ISL8391 has four normally closed （NC） switches; the ISL8392 has four normally open （NO） switches; the ISL8393 has two NO and two NC switches and can be used as a dual SPDT， or a dual 2:1 multiplexer. Table 1 summarizes the performance of this family. For higher performance， pin compatible versions， see the ISL43143-5 data sheet.
