Well I completely stuck with the explanation of this circuit as an a-stable multivibrator **broken link removed** can anyone tell me if the explanation in the link is relevent for the IC SN7400. I can see the top half of the layout is identical to the bottom half and that is where my understanding ends. I have been reading a book called Higher Electrical Engineering by J sheperd,AH morton & L F spence and I've found an a-stable multivibrator on page 737 that looks pretty similar to this diagram https://www.aaroncake.net/circuits/inverter.asp I've learned its junk but is it in theory an a-stable multivibrator. The Book quotes a a stable multivibrator as"two RC coupled stages are given 100 percent feedback and this gives rise to conduction process wherby one stage is fully conducting while the other is switched off, conduction being transferred from one stage to the other by the discharge of a capacitor through a resistor" does anyone have a simple answer to what is happening at the left hand end of the circuit in the first link. Am I missing the simplicity of it?
