Simple Square Wave Generator with 7400


Posted on Feb 6, 2014

This is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications. The output freq. is dimensioned through the RC components and time delay of the 3 inverter gates. The time delay of a logic gate is the elapsed time

between a change of input state and the resulting change of the output state. To prevent the temperature and voltage supply from affecting the frequency of the square wave generator, the oscillator freq. fo must be smaller than 1/2tpn where:
