Obviously not, 74 are all digital logic circuits, can not be operational amplifiers, operational amplifiers belong to analog circuits.

Check for you, 74LS145 is a 4-10-line decoder (with a drive), the following is the truth table. The chip has a total of 16 pins, 16 and 8 are the power supply and ground, the 15-12 pins correspond to P0-P3, the 1-7 pins deal with Q0-Q6, and the 9-11 pins correspond to Q7-Q9
