555 Astable Multivibrator

Description

SPICE simulation of a square wave generator with a frequency fixed by the external components to IC 555.F= 1.45/[(RA+2*RB)*Ct].The time when the output is high is given by Th= 0.693*(RA+RB)*Ct, the time when the output is low is Tl= 0.693*RB*Ct.The total period T = Th + Tl = 1/F.
