BJT Astable Multivibrator

Postby neoply » May 23rd, 2017, 1:16 am

Hello all. Thanks for taking up your time to read my post.


I have the basic knowledge about multivibrators, but I did not understand the working principles of the circuit schematic provided down below.

I have done the basic research about how it works, but I could not understand this particular BJT Astable Multivibrator circuit. Could someone please explain why 470 ohm and 10K ohm resistors in the SN74LV123ANSRG4 as the datasheet of http://www.kynix.com/uploadfiles/pdf8798/SN74LV123ANSRG4.pdf are used and why the outputs of the circuit are not the emitter legs of the transistor but the collectors of the transistors.


And the most important question is : I put LEDs to the outputs. Does that changes the duty cycle of the Multivibrator (or frequency) ?


Can anyone help me ? I am very puzzled about this question.
