&nbsp;較寬的工作電壓:2~6V </p> <p> ? &nbsp;相與的串行輸入,直接的清零信號 </p> <p> ? &nbsp;輸出能驅動 10 個 LSTTL 負載 </p> <p> ? &nbsp;封裝型式:DIP14 / SOP14 </p> <p> <br /> </p> <img src="http://statics.xiumi.us/stc/images/templates-assets/tpl-paper/image/917775998d646271c46a7b375b598a39-sz_2676.gif" /> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 功能框圖及引腳說明 </p> <p> 功能框圖 </p> <img src="http://img.xiumi.us/xmi/ua/NSM2/i/c6ca89eb2c6e242d93ba93c23fb0ad15-sz_21361.jpg?x-oss-process=style/xmorient" /> <p> <br /> </p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;引腳排列圖 </p> <p> Tips1:鼠標左鍵單擊文字就可以編輯 </p> <p> Tips2:雖然文字可以多行書寫 </p> <p> 但是這個歌詞模板建議每個序列模塊只寫一行 </p> <p> Tips3:打開布局模式,第二層布局的灰色邊緣 </p> <p> 便可調出滑動工具條 </p> <p> 點擊設置滑動序列 </p> <p> 然后可以刪除不需要的序列 </p> <p> Tips4:打開布局模式后 </p> <p> 點擊最里面的一層布局,并復制 </p> <p> 然后點擊第二層布局,設置滑動序列 </p> <p> 點擊剪貼板中復制的樣式 </p> <p> 就可以添加新的序列 </p> <p> 左方顏色要與前一個布局的右方顏色保持一致 </p> <p> 右方顏色要與下一個布局左方的顏色保持一致 </p> <p> ***** </p> <img src="http://img.xiumi.us/xmi/ua/NSM2/i/09d305b3a263c22123e0181573e001e7-sz_9192.jpg?x-oss-process=style/xmorient" /> <p> &nbsp;引腳說明及結構原理圖 </p> <img src="http://img.xiumi.us/xmi/ua/NSM2/i/965aae44efb93dfad0857c3f5717f408-sz_23195.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/392ed49b72419d4dffcb9600706f0543-sz_16865.jpg?x-oss-process=style/xmorient" /> <p> 注:H:高電平 </p> <p> h:時鐘上升沿前建立起來的高電平電壓 </p> <p> L:低電平 </p> <p> l:時鐘上升沿前建立起來的低電平電壓 </p> <p> q:對應于時鐘上升沿時,前面一個寄存器的狀態 </p> <p> ↑:時鐘上升沿 </p> <p> <br /> </p> <p style="text-align:center;"> ◆ ◆ ◆&nbsp;◆ </p> <p> 電特性 </p> <img src="http://img.xiumi.us/xmi/ua/NSM2/i/bf0534758f3133bd235b64de17a74320-sz_50772.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/fedc45f640a39dbf3f9f7c97852c8012-sz_17963.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/3a63c8c0dae3456a93052f4b371e7630-sz_40760.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/3a63c8c0dae3456a93052f4b371e7630-sz_40760.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/972e616d1a55ab36415d9b696a02e752-sz_41514.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/7114bb33dd8c5c01afd4f08df9c601b8-sz_38653.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/1ebef0ef36ea6a789b7f95ac819fea19-sz_14234.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/e66a7c27ea3a175850f05ad11e810a63-sz_28712.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/73f10c232636c8cd6671ad4968a4a39a-sz_38109.jpg?x-oss-process=style/xmorient" /> <p style="text-align:center;"> ◆ ◆ ◆&nbsp;◆ </p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;封裝尺寸與外形圖 </p> <p style="text-align:center;"> ◆ ◆ ◆&nbsp;◆ </p> <p> <img src="http://img.xiumi.us/xmi/ua/NSM2/i/a3e9dc6b7561d4e9bb872628673b6b0b-sz_59585.jpg?x-oss-process=style/xmorient" /><img src="http://img.xiumi.us/xmi/ua/NSM2/i/9ae5e2a74cdc5fda4e5f74b2707ae648-sz_31898.jpg?x-oss-process=style/xmorient" /> </p> <p> <br /> </p> <p> <img width="500" height="83" alt="" src="http://img.xiumi.us/xmi/ua/NSM2/i/7215cf86e30c719687d1af1d900e6c94-sz_206572.png" /> </p> <p> <img width="500" height="127" alt="" src="http://img.xiumi.us/xmi/ua/NSM2/i/16e672833b64d28b9d089e653d4e022b-sz_83925.png" /> </p> <p> 請留下你指尖的溫度 </p> <p> 讓太陽擁抱你 </p> <p> <strong>記得這是一個有溫度的公眾號</strong> </p> <img width="500" height="500" alt="" src="http://img.xiumi.us/xmi/ua/NSM2/i/fc4100317041594fbef5231216ae8188-sz_25267.jpg?x-oss-process=style/xmorient" />
