What is the output frequency for a 74LS14 astable multivibrator circuit if R equals 330?

Answer 1

The output frequency of a 74LS14 astable multivibrator can be calculated using the formula ( f = \frac{1.44}{(R_A + 2R_B)C} ), where ( R_A ) and ( R_B ) are the resistances connected to the circuit and ( C ) is the capacitance. Assuming ( R_A ) is 330 ohms and ( R_B ) is also 330 ohms (if not specified, we can assume this for calculation) and using a typical capacitor value (e.g., 100 nF), the frequency can be calculated. For example, if ( R_A = R_B = 330 , \Omega ) and ( C = 100 , nF ), the frequency would be approximately 4.4 kHz. Adjust the values of ( R_B ) and ( C ) for specific calculations.
