Hi this is my first post, i hope i'm in the right place.... I'm trying to convert Y=(A'CD+B'CD')'' into a logic symbol drawing i'm supposed to do this and then build a circuit using 3 input NAND gates with chips 74HC11 and 74HC04 (inverter).

The first thing i wanna get straight is if it would be correct to cascade two 3 input nand gates or one on top and one on bottom conecting them to an OR gate??

Show your schematic. If by cascading you mean two seperate gates positioned one above the other then yes. I'm thinking cascading means something different when used with electronics.

When you reply to a message, you will notice the Browse and Add this attachment buttons just above the Add post button.

When you browse, you will be searching your machine for a file to attach.

If your using a schematic capture program, you can copy and paste [or save the schematic as a graphic] the schematic to your graphics program and save the graphic. You would browse to that graphic, select it, and Add this attachment.

Then you can post your message.

Below is a thumbnail of a circuit I've posted before.

When you click on the attachment it opens to another window, full size.
