8-Input Data Selector/Multiplexer With 3-State Outputs

The IN74HC251 is identical in pinout to the LS/ALS251. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The device selects one of the eight binary Data Inputs, as determined by the Address Inputs. The Output Enable pin must be at a low level for the selected data to appear at the outputs. If Output Enable is high, the Y and the Y outputs are in the high-impedance state. This 3-State feature allows the IN74HC251 to be used in bus- oriented systems. By Integral Corp.
