Multiplexer

A digital multiplexer selects from a number of inputs and switches it to one output. Here you find everything about digital multiplexer and its counterpart, the digital demultiplexer. » more...

Comparator

A comparator compares two input voltages and gives you, as a result, which of the voltages is higher. It is used in controllers, in analog to digital converters and a frequency counter. Here you find out why. » more...

Flip-Flop

Flip-flops are "smart" electronic circuits. They control lifts, traffic lights and make sure computers never forget a number. Here you find out what makes them "smart", how to set up circuits and where they are used. » more...

Multivibrator

Multivibrators are frequently used in electronic circuits. You can find them in many different versions as blinkers, signal delay and in digital electronics. Find out everything worth knowing here. » more...

Timer 555

Timer are very common integrated circuits and can be found in various applications, from toys to complex control systems. Here you get to know the NE555 timer. » more...

Darlington Pair

In some cases, the gain of a single transistor is not sufficient to amplify a signal. In that case, you can create a circuit of two transistors, the so-called Darlington pair. » more...
