DM74ALS253N

3-STATE Dual 1-of-4 Line Data Selector/Multiplexer

General Description This Data Selector/Multiplexer contains full on-chip decoding to select one-of-four data sources as a result of a unique two-bit binary code at the Select Inputs. Each of the two Data Selector/Multiplexer circuits have their own separate Data and Output Control inputs and a no

DM74ALS257

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.
