Hey all, Im looking for something thats like a buffer. Ok what i need is a IC that will take a parallel input... at least 8 bits and store it on its output when i latch it...

Like ...

I set PORTA on my PIC to 0x01 and latch the IC so i can then change PORTA to 0x02 and the IC still has 0x01 on its output until i latch the 0x02...

What can do this?

Octal latch. Made in several logic families. Part# usually ends in '373

My goal is i latch the data to all of them but only output to 1 then latch to all and output to another etc.... Since the internal info doesnt affect the OUTPUTs...

The 373 is a common latch, it works like eight D flip-flops. It's also tri-state. Really popular part in old computers. Should work exactly as you expect.
