SI2301在这幅图的作用是什么。这是复位电路吗？百度知道
答：当作一个开关管用。座子是电源插针。按键按下SI2301关闭，VCC断电。按键松开，SI2301导通，VCC得电。

DESCRIPTION
The DG444/DG445 monolithic quad analog switches aredesigned to provide high speed, low error switching of analogsignals. The DG444 has a normally closed function. TheDG445 has a normally open function. Combining low power(22 nW, typ) with high speed (tON: 120 ns, typ), theDG444/DG445 are ideally suited for upgrading DG211/212sockets. Charge injection has been minimized on the drain foruse in sample-and-hold circuits.To achieve high-voltage ratings and superior switchingperformance, the DG444/DG445 are built on Vishay Siliconix’shigh-voltage silicon-gate process. An epitaxial layer preventslatchup.

1 SDN I Shutdown Input Pin.0–VDD V digital input. SDN should be = 0
in all modes except Shutdown mode.When SDN = 1, the chip will
be completely shut down, and the contents of theregisters will
be lost. 关闭输入Pin.0-VDD V数字输入。SDN应该在所有模式除了关机模式= 0。SDN = 1时,芯片将被完全关闭,theregisters的内容将丢失。

so the L-C match must supply VDD (+3.3 VDC nominal) to this
pin. 传输输出接脚。巴勒斯坦权力机构的输出是一个排水明沟连接,所以L-C匹配必须提供VDD这个销(+ 3.3 VDC名义)
