#217 Help with AND gate symbol
Matt,
I told you that I figured out how to change the pin numbers on the gates in Tiny Cad - this was true. I am designing a unique circuit and needed to use some AND gates, XOR gates and HEX inverters - I am using CMOS chips. I mistakenly used the symbols for TTL logic parts and printed a design where AND gate B of the CMOS 4081 chip came out with input pins 4 & 5 and output pin 6 and it should have been input pins 5 & 6 and output pin 4. How do you go about adding CMOS packages to the library?
You will have to make you own version of the 4081. Follow the instructions in the Wiki to create your own library. Export the AND gate from the 74 library and import it in to your new library. Edit the pin numbers. Save the part.
Once you have your new part go to your schematic and right click on the AND symbol, and select "Replace Symbol". Replace you existing symbol with your new one, and all should be well.
