附錄I 555集成電路基本資料（返回）555是美國(guó)SIGNETICS公司1972年開(kāi)始推出的集成電路，它的使用十分廣泛。目前全世界已有很多公司生產(chǎn)。在555型號(hào)前面一般會(huì)有生產(chǎn)廠商的標(biāo)記，如SE555、5G555、NE555、LM555、卩A555、XR555等。555集成電路內(nèi)部包含有兩個(gè)電壓比較器，一個(gè)RS觸發(fā)器，一個(gè)放電管和一個(gè)輸出級(jí)。圖1.1 555集成電路內(nèi)部框圖其內(nèi)部電路見(jiàn)圖I.1，最常見(jiàn)封裝的引腳排列見(jiàn)圖I.2。555集成電路的第8腳是電源端，接電源正極，第1腳是公共接地端，接電源負(fù)極。從555集成電路內(nèi)部電路分析，第2腳是低觸發(fā)端，第6腳是高觸發(fā)端，第5腳是比較觸發(fā)的控制端，我們把第5腳的控制電壓記作Vcv,如果第5腳只是接一個(gè)電容器到地，這時(shí)第5腳的控制電壓Vcv=（2/3）Vcc，如果第5腳接到一個(gè)固定電壓上，則控制電壓Vcv就等于該固定電壓。一般情況下，第6腳的輸入電壓小于Vcv,第2腳的輸入電壓大于Vcv/2,這時(shí)比較器1和比較器2都輸出高電平，從而對(duì)RS觸發(fā)器不發(fā)生影響，555的輸出狀態(tài)不變。當(dāng)?shù)?腳高觸發(fā)端的輸入電壓大于Vcv時(shí)，比較器1就會(huì)輸出低電平，從而使RS觸發(fā)器輸出高電平，導(dǎo)致放電管導(dǎo)通，555第3腳輸出低電平；而當(dāng)?shù)?腳的輸入小于Vcv，第2腳低觸發(fā)端的輸入電壓小于Vcv/2時(shí)，比較器2又會(huì)輸出低電平，從而使RS觸發(fā)器輸出低電平，導(dǎo)致放電管關(guān)斷，555第3腳輸出高電平；第4腳是低電平復(fù)位端，一般情況下第4腳接高電平。當(dāng)?shù)?腳接低電平時(shí)，觸發(fā)輸入和控制的2、5、6腳將不再起作用，此時(shí)放電管導(dǎo)通，555第3腳輸出低電平。555集成電路的生產(chǎn)廠家很多，各個(gè)廠家生產(chǎn)的參數(shù)差異不大，我們?cè)诒鞩.1中列出了SE555集成電路的部分參數(shù)。GND[1TRIG[2GND[1TRIG[2OUT[3RESET[4SIGNETI555圖1.2555集成電路引腳排列表I.1 SE555集成電路的部分參數(shù)（返回）參數(shù)條件最小值典型值最大值電源電壓Vcc4.5V18V電源電流Vcc=5V,輸出低，空載3mA6mAVcc=15V,輸出低，空載10mA12mA5?15V,輸出高，空載1mA初始定時(shí)精度C=0.1卩F0.5%2%觸發(fā)電流0.5pA復(fù)位電壓0.4V0.7V1V復(fù)位電流0.1mA0.4mA輸出低電平電壓Vcc=15V，吸10mA0.1V0.15VVcc=15V，吸50mA0.4V0.5VVcc=15V，吸100mA2V2.2VVcc=15V，吸200mA2.5VVcc=5V,吸8mA0.1V0.25V輸出高電平電壓Vcc=15V,放200mA12.5VVcc=15V,放100mA13V13.3VVcc=5V,放100mA3V3.3V輸出上升時(shí)間100nS輸出下降時(shí)間100nS附錄J CD4017集成電路基本資料（返回）CD4017是CMOS數(shù)字集成電路，它的使用十分廣泛。目前全世界已有很多公司生產(chǎn)。在4017型號(hào)前面一般會(huì)有不同的標(biāo)記，如CD4017、CC4017、TC4017、HD14017、MC14017o5102673sQQQQQQQVs■^1M討一強(qiáng)口nl
