74LVQ151 Datasheet | Fairchild Semiconductor

Description The LVQ151 is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one line of data from up to eight sources. The LVQ151 can be used as a universal function generator to generate any logic function of four variables. Both true and plementary outputs are provided. Features n Ideal for low power/low noise 3.3V applications n Guaranteed simultaneous switching noise level and dynamic threshold performance n Guaranteed pin-to-pin skew AC performance n Guaranteed incident wave switching into 75Ω Ordering Code: Order Number 74LVQ151SC 74LVQ151SJ Package Number M16A M16D Package Description 16-Lead (0.150" Wide) Small Outline Integrated Circuit, SOIC JEDEC 16-Lead Molded Small Outline Package, SOIC EIAJ Devices also available in Tape and Reel.

Both true and plementary outputs are provided. The Enable input (E) is active LOW. When it is not activated, the plementary output is HIGH and the true output is LOW regardless of all other inputs. The logic function provided at the output is: Z = E - (I0 - S 0 - S 1 - S 2 + I1 - S0 - S 1 - S 2 + I2 - S 0 - S1 - S 2 + I3 - S0 - S1 - S 2 + I4 - S 0 - S...
