555 Timer

ravenprp

Hi, I have a 555 timer IC. For my work, my colleague asked me to make it so it can output 100 KHz frequency. (astable)

My Ra = 6.8 kOhms and my Rb = 4.7 kOhms...

I know that the Frequency = 1 / (T_high + T_low) where

T_high = 0.693(Rb + Ra) * C
T_low = 0.693(Rb) * C

Although I'm not too sure what to do from there.

Any help?

Do you have the datasheet with the design guidelines? That's the best place to start. If you have specific questions about the datasheet's guidelines, can you post a pointer to the datasheet, and I'll take a look.

I got it, nevermind. Thanks though :)
