f : 640k Hz

D : 50%

f : 640k Hz

tH + tL = D = 50% ( D = 50% = 50% =

t = 7.8125 x Misal :

VOH = 5V

VOL = 0V

VT+ = 2.75V

VT- = 1.67V

Vcc = 5V

Maka : V = VT+ VT-

V = 2.75 1.67 = 1.08V

E = Vcc VT-

= 5 1.67

= 3.33V

t = R. c. ln

Jika R = 1k

t = 1k x c x ln 7.8125 x = 1k x c x ln 7.8125 x = 1k x c x (0.393)

c =

= 19.87 x F

Sehingga

R = 1k c = 19.87 x F
