I have a Schmitt Trigger with an op.amp.
If i try to drive a TTL AND with the output of this op.amp. I got nothing.
Was wondering, how (if) I can drive a digital input (gate) with an analogue signal.
Thanks in advance

Please elaborate on what you are attempting. You just connect them. Do you have enough signal?

When you say an opamp, what part are you using? Sounds like you grabbed some non-simulation part, or you don't have power supplies on the opamp or something...
