Hi everybody,

I am new to this forum and also to digital world. This is my first question.

Could you please tell me how I implement AND gate? (transister needed?)

Thank you

 

This is a situation where Wikipedia works. The kind of logic would help, too. The one shown in the link is different from an RTL gate, or DTL, or TTL.

 

A very simple AND gate can be created using only diodes and one resistor. One end of resistor tied to Vcc, diode cathodes tied to resistor. Output is taken from that junction and inputs are placed on diode anodes. If any anode is at ground, output will be 0.7v. All inputs need to be hi for output to be hi.

 

 

I prefer CMOS technology. I know it doesn't have any transistors, but from the OP, it didn't seem mandatory.

Google's first result: Your trusty AAC!

EDIT: When I said CMOS technology doesn't have transistors, I meant BJT ones.

 

I like RTL myself...
