Here it is, a three input AND gate. You can often find such a gate in one package, and even higher.

I had prepared something for max but might be also for you, buggzy, sorry http://everycircuit.com/circuit/5122305819148288

Homework for Buggzy, try to make a triple input NAND gate. I m sure you will find out whats wrong.

NAND gate? He wants an AND gate. And these resistors are not needed in TTL logic. Only CMOS requires a bleeding resistor.

EC doesn't cope well with ungrounded inputs on such devices, not that it's not possible

TTL open inputs are defined as HIGH and not as LOW my little slippery snake ;-)

Be that as it may, as far as EC is concerned, the resistor is not needed. In reality, every circuit needs a ground reference. I don't see anything worthy of your bickering ;)

Btw, hurz you are almost correct, but just like you thebugger, your supposed to use ——>>3<<—— >>AND GATES<<——.

I cant afford 3 gates, the wife gave me a budget and i can only buy two.

Most of the times there are 4 or more gates in one package.
