hey i am designing a microcontroller system that uses a ccd and memory to store the image. i need something that selects an address bus from two separate 16 bit address buses. curently,i am using two tristate latches whose outputs are shorted. i also need the reverse thingy..a component that connects a bus to any of the two output buses depending on the select line.again ,here i am currently using two latches. i know that what i am talking abt correlate with mux-demux but i need 16bit and 8 bit version of the component. i tried searching on the net but ended up on a page where some other person is looking for a similar thing.
