Can anybody fix the model. Sounds like you are asking for an obvious feature of the said chips. Which P-channel mosfets are you using – in particular, are they meant for 5V gate drive, and do they have a low enough Rds on at 1.

How to control the outputs by using one line for all the 3 ENx pins? Don’t use if can be helped.

Yes, logic outputs are best protected from current spikes caused by trying to try and drive a capacitance of more than a couple of hundred pF. I need extra NOT gates?. E1 to E3 are just arbitrary names. Does it datashewt if I use a 74hc, 74hct, 74ac, etc.?

While I agree with the above statements, none of them actually answer the OP’s original question.

I need to datasueet turn off the outputs without changing the output state i. I believe that ‘ style encoders only have 1 pin true at a time, meaning you’ll need to continually scan the Leds, You might be better off using 8-bit latches instead.

There is also the ‘ series of 4 line to 16 line decoders. Synthesized tuning, Part 2: KeithRB on Nov 07, Please do not ask for unpaid help via PM, use the forum.
