Four bits of data from two sources can be selected using a common data select input. The four out- puts present the selected data in the complement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
