Hey guys another question. How do i combine 74LS138's to make a 1-of-16 decoder. Is it as simple as connecting two of the three inputs from one 74138 to determine which of the decoder chips to enable (say A4 is the MSB with A3). These will connect to the seperate enable inputs (E1 and E2) with possibly an inveter on E2 to simulate a high when needed. E3 will be earthed i think???

And then have all three other inputs to determine which output of the enabled chip is determined (A2, A1, A0).

Will this work

Thanks

Probably will work. A schematic makes all clear.
