Logic probe by IC 4050

When you learn digital circuit necessary tool for check logic of the digital. May flee don’t pass Logic probe for extremely amateur type our electronics emphasize economize keep before. I has interesting circuit comes to present be Logic probe by IC 4050 by pillar equipment be IC CMOS 4050 or CD4050 or LM4050. Be the integrated circuit gate buffer logic. I uses just one part or 1/6 only. From the circuit LED stick bright when input = logic low only.

Logic Probe by 74LS47
This circuit is a Logic Probe. It indicates the logic state of the node of any TTL logic circuit. To do that, we have to supply the probe with the same power of the circuit that we want to ana ...
Audible Logic Probe
When testing circuits with a logic probe, it is sometimes difficult to watch the LEDS on the probe to determine the logic state. With this probe the logic states are audible. This probe is des ...
