8-Input Data Selector/ Multiplexer with 3-State Outputs High−Performance Silicon−Gate CMOS MC74HC251A The MC54/74HC251 is identical in pinout to the LS251. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device selects one of the eight binary Data Inputs, as determined by the Address Inputs. The Output Enable pin must be a low level for the selected data to appear at the outputs. If Output Enable is high, both the Y and the Y outputs are in the high−impedance state. This 3−state feature allows the HC251 to be used in bus−oriented systems. The HC251 is similar in function to the HC251 which does not have 3−state outputs.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.
