555定時器是一種集成電路芯片,常被用于定時器、脈沖產(chǎn)生器和振蕩電路。555可被作為電路中的延時器件、觸發(fā)器或起振元件。下面我們來看看555定時器引腳圖和555芯片的引腳參數(shù)及功能。
555引腳圖
一、555定時器引腳功能:
引腳1:GND(地),功能:接地,作為低電平(0V)
引腳2:TRIG(觸發(fā)),功能:當此引腳電壓降至1/3VCC(或由控制端決定的閾值電壓)時輸出端給出高電平。
引腳3:OUT(輸出),功能:輸出高電平(+VCC)或低電平。
引腳4:RST(復(fù)位),功能:當此引腳接高電平時定時器工作,當此引腳接地時芯片復(fù)位,輸出低電平。
引腳5:ctrl(控制),功能:控制芯片的閾值電壓。(當此管腳接空時默認兩閾值電壓為1/3VCC與2/3VCC).
引腳6:THR(閾值),功能:當此引腳電壓升至2/3VCC(或由控制端決定的閾值電壓)時輸出端給出低電平。
引腳7:DIS(放電),功能:內(nèi)接OC門,用于給電容放電。
引腳8:V+,VCC(供電),功能:提供高電平并給芯片供電。
