ISL43140中文資料Intersil數據手冊PDF規(guī)格書

The Intersil ISL43140–ISL43142 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 (1?W), low

leakage currents (1nA max), and fast switching speeds

(tON = 30ns, tOFF = 18ns). A 12? maximum RON flatness

ensures signal fidelity, while channel-to-channel mismatch is

guaranteed to be less than 2.5?. The 3mm x 3mm Quad NoLead Flatpack (QFN) package alleviates board space

limitations, making this newest line of low-voltage switches an

ideal solution.

The ISL43140/ISL43141/ISL43142 are quad single-pole/

single-throw (SPST) devices. The ISL43140 has four normally

closed (NC) switches; the ISL43141 has four normally open

(NO) switches; the ISL43142 has two NO and two NC

switches and can be used as a dual SPDT, or a dual 2:1

multiplexer.
