WhatRoughBeast 49k 2 28 And that’s what is going on with the The demultiplexing function is performed datxsheet using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low.
Home Questions Tags Users Unanswered. There are probably two enable inputs because otherwise there would be two datashet pins on the 24 pin package I don’t recall seeing 22 pin DIP packages. As for the NAND gates, there is a vatasheet being implemented in which the gates are there to realize it.
If you want to know exactly what is going on then draw out the truth table, but it is unlikely their function will make much sense to you.
So you can use a 47 kilohm resistor to pull up drops 1. Sign up using Email and Password. Home Questions Tags Users Unanswered.

The active-low output is just how the design for datasyeet specific decoder was carried out – there is also active-high varieties. Post as a guest Name. This allows more flexibility in the logic functions available. These demultiplexers are ideally suited for implementing high-performance memory decoders.
This all has to datashest with the actual ic design. Sign up using Email and Password. When either strobe input is high, all outputs are high.
However, due to the daatsheet structure of theonly one output can be enabled at a time. You can upvote more than one answer. That is, if the outputs were active high, OR gates would perform the synthesis desired. I am a new user so I didn’t know I had that power. High speed signals were usually datashdet low, for much the same reason.
The person who took time to answer the question will appreciate that. This carried through to the input current requirements: Inputs were pulled high by default, and only pulled low when necessary, to save power.
