I need help wiring my 555 timer in an astable configuration with a 50% duty cycle at 100 kHz. Here is a link to the timer I am using:
https://www.digikey.com/product-detail/en/fairchild-on-semiconductor/LM555CN/LM555CNFS-ND/458696
I am applying a constant DC 6-volt input to the timer. I originally wired the timer as shown in this link:
http://www.learnabout-electronics.org/Oscillators/osc44.php
However, while I am getting an AC square wave from the timer, the duty cycle is much closer to ~66%. My resistor and capacitor values are:
R1 = 72 ohms
C1 = 10 nF
C2 = 100 nF
based on Figure 4.4.6 in the link above. Can someone tell me what's happening? Thanks.
