This data selector / multiplexer contains inverters and drivers to supply full on-chip data selection to the four output
gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four
outputs. Then, outputs present inverted data to minimize propagation delay time.
