本刊2000年第8期苏成富先生的“巧用D触发器”一文,经阅读、分析,认为其中“恒温电路”和“水位控制电路”不能正常工作。经按图组装试验同样证明上述电路不能正常工作。 1.D触发器用途极广,除可以组成双稳态电路、单稳态电路、无稳态电路外,还可转换成JK触发器,R-S触发器等电路。但是不论组成什么电路,其基本的逻辑功能特性是不变的。反映D触发器的逻 The magazine in 2000 No. 8 Mr. Su Chengfu’s “clever use of D flip-flop,” a text, after reading, analysis, that “thermostat circuit” and “water level control circuit” can not work properly. The same assembly test by the same proof that the above circuit does not work. 1.D triggers a very wide range of uses, in addition to form a bistable circuit, monostable circuit, no steady-state circuit, but also can be converted into JK flip-flop, R-S flip-flop and other circuits. However, no matter what circuit is formed, its basic logic function is unchanged. Reflects the D flip-flop logic
