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 complementary outputs are provided. Features s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Guaranteed incident wave switching into 75 Ordering Code: Order Number 74LVQ151SC 74LVQ151SJ Package Number M16A M16D Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Devices also available in Tape and Reel. Specify by appending suffix letter "X" to the ordering code.

Both true and complementary outputs are provided. The Enable input (E) is active LOW. When it is not activated, the complementary 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 1 * S2 + I5 * S0 * S 1 * S 2 + I6 * S 0 * S1 * S2 + I7 * S0 * S1 * S 2) The LVQ151 provides the ability, in one package to select from eight sources of data or control information. By proper manipulation of the inputs, the LVQ151 can provide any logic function of four variables and its complement.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: Unused inputs must be held HIGH or LOW. They may not float.
