| Posted: 17 May 2013 09:24 AM PDT They are digital logic probe circuits that you make easliy. Most digital circuits that used CMOS ICs. because I like using CMOS ICs. Because it needs a voltage of approximately 3V to 12V and the power consumption is low. If we use the battery power for longer than IC-TTL. But when problems need to Logic. We use a CMOS IC is suitable or more efficient. And in the third circuits. We use the display with sound. Is so easy to use.There are 3 circuits, as follows. (see below!) 1.Three state logic tester probe using IC-CD4001 The work of the Temple three state logic IC-CD4001 circuit be the circuit will use not gate IC in show supervision. In case of still have no input signal come in be liberate input pin of IC1/1 float keep. Which make have impedance very many, which have no LED anything shine come out. In first [...]  |
