3-STATE Quad 1-of-2-Line Data Selector/Multiplexer General Description These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four 3-STATE outputs that can interface directly with data lines of bus-organized systems. A 4-bit word selected from one of two sources is routed to the four outputs. | FairchildFairchild Semiconductor 仙童半导体飞兆/仙童半导体公司 |   | ||
