Hi all,

Have a question here. In the attachment there shows 4 NAND gates. Do you guys know how I can determine which is those each pins on the IC?

Because I try to find on the datasheet but didn't manage to find the pin configuration for the connections in the attachment?
Appreciate you guys' help.

Thank you.

All datasheets show the pin numbers for each of the 4 gates in the package.

thanks for reply. But how can i know which puns correspond to which NAND gate?
what i mean is for example, pin A0, B0 and O0 correspond to which NAND gate in the circuit?

or every NAND gate is the same one?so we can ramdomly connect them?

They are all the same! - use the ones that make the PCB layout easier.

noted Sir.

Thanks Nigel and audioguru very much

Nand Gates

You would go in on 1 and 2 out on 3 = 1 nand gate
in on 4 and 5 out on 6 = 1 nand gate
in on 12 and 13 out on 11 = 1 nand gate
in on 9 and 10 out on 8 = 1 nand gate

Pin 7 goes to GND and Pin 14 goes to +

These nand gates could also be tied together to form any other gate like the:

Inverter, AND, OR, NOR, XOR, and the XNOR.

You would need 5 nand gates to make 1 XNOR gate, the 7400 only has 4 nand gates so you would need one more nand gate to form the XNOR. Every other logic function gates can be made with 4 or less nand gates.
