I need a thing (=preferably 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?
