I need a thing (preferably a single IC) that has 8-bit input, 8-bit output and a control bit, with this behaviour:

• if control bit active, set output bits to inputs (no need to actually conduct through, as long as they have the correct (0-5V TTL compatible) signals

• if control bit inactive, set output pins to high impedance so they don't interfere with other stuff.

So essentially a "bus output enable/disable gate".

I don't seem to find any, maybe i'm searching for the wrong keywords. Anyone have an idea?
