The MC14034B is a bidirectional 8bit static parallel/serial, input/output bus register. The device contains two sets of input/output lines which allows the bidirectional transfer of data between two buses; the conversion of serial data to parallel form, or the conversion of parallel data to serial form. Additionally the serial data input allows data to be entered shift/right, while shift/left can be accomplished by hardwiring each parallel output to the previous parallel bit input.
