Are there AND logic gates besides the 74HC08 that are more suitable for two inputs? My two inputs are wide impulsions and a high frequency signal.

 

Are they logic level signals? How high is the frequency?

 

What's a wide impulsion? A low-frequency gating signal?

What is the high frequency range that you are speaking of? Is it a square wave?

Are they both approximately the same amplitude, like TTL level?

It would be helpful if you could post sample images of your input signals, or at least describe them thoroughly.

One option might be to use a high-speed comparator. An LT1016 has unity-gain bandwidth of 200GHz. Yes, GHZ.
