【正文】 555定時器，制作信號發(fā)生器，只需外接幾個電阻、電容，就可以實現(xiàn)多諧振蕩器、單穩(wěn)態(tài)觸發(fā)器急施密特觸發(fā)器等脈沖產(chǎn)生信號與變換電路。經(jīng)測試，接通電源后通過調(diào)節(jié)電位器既可以調(diào)整方波的頻率，也可以調(diào)整波形的占空比。555時基電路是一種將模擬功能與邏輯功能巧妙地結(jié)合在同一硅片上的組合集成電路。關(guān)鍵詞：NE555。方波 ABSTRACTUse 555 timer, making signal generator, need to external several resistor, capacitor, it can achieve more harmonic oscillator, single state trigger urgent Schmitt toggle etc pulse signal and transform circuit. By test, put through power supply by adjusting the potentiometer can adjust the frequency of square wave, also can adjust the waveform v. With 555 production signal generator with low cost and reliable performance advantages. 555 the circuit is a kind of function and the logical function simulation ably bined with the bination of in the same slice of silicon integrated circuits. This circuit can again the most basic way the typical application of foundation, according to the actual need, after parameters of the circuit configuration and new bination, and external a small amount of resistance and capacitance ponents can constitute a different circuit, and 555 in the produce and waveform circuit transformation, measurement and control, home appliances, electronic toys
