Hello, I'm a real beginner at this so I thought I'd need some input before I start wasting my money.

I have a short signal (about .2V) which need to be amplified to TTL level and then make it stay on logic 1 for a few microseconds. I thought of using a comparator for the amplification, but I'm not sure what to do next. The original signal is only some nanosecond long so I guess I need a flip flop or something. Any ideas on what to do, or suggestions on books or articles?

I would put this signal (.2V) in a transistor to switch 0 or 5V into a TTL input. How many nanoseconds is your original signal?

To have a TTL signal in the output for a few microseconds, use the CD4060 that is a decade divider. You can input signals like 0 or 5V (if you are using +5Vcc).

Good luck!
