Your word choices are quaint to say the least. Most test and programming fixtures implement a pin driver for each pin on the ZIF socket. The purpose of a pin driver is to make each pin capable of being an input or an output or a power pin. I know of no reason why a single chip could not be created for such a purpose, but at this time I know of no such chip. In commercial programmers and test fixtures each pin requires several circuits to do the job. I can think of numerous ways to design pin drivers, but I think it comes down to cost. How much are you willing to spend on parts and board area for each pin.
