Without any unnecessary details- A regular demultiplexer can only have one output set, the rest of the outputs at that time are pulled high (for example). What I am asking for, is there a demultiplexer, where the outputs dont go high, but keep their state for the time before I amnually update it.
For example, there is a 16 bit output demultiplexer. I choose address 0 and place value low, that means output 0 gets low and the bits from 1 to 15 remains high. Now I change address to 1 and insert low value. Output 1 gets low but the output 0 doesnt keep its 0 value, but turn high. This is for a regular demultiplexer. I need a device that will keep the set values.
