Give the information of IC HD74L and it's application (what we can do from it) those who will give right answer I will consider him brainliest.

Answer:
What you feel is very natural. After all you are a 1st year student. But you don't have to get frustrated. Have you been taught about ICs, have you been taught about IC Technology? No, right? So, obviously you won't won't know. But since you are thinking about it and willing to know, you will.
Purpose of ICs are to make our life easier, specially in projects and application. The name itself is Integrated Circuit, which means circuits have been Integrated inside the chip to perform some specific function.
As a beginner, this was my approach. I learned about two ICs, IC741 (Op-amp) and IC555 (timer). The reason being, these two ICs are so versatile that I could literally do everything with these two.
So here is what you should do. Learn about Op-Amp first. Then learn about IC555.
Now, when you start any project, think about what you want to do. How will you arrive at the final step and the step before that. Once you have broken it into steps, try to achieve those results with ICs one step at a time.
But, you might need to work on different ICs too. Now, the thing is, there are thousands of ICs and no engineer can guarantee that they know how to work with all of them. You will have to Google them.
For example you want to work on gas based project which involves sensing of gas. Google 'gas sensors'', you will get many IC names. Note few of them down. For example you got ICxyz. Now Google again, , 'ICxyz datasheet', download the PDF and here is where you will get each and every detail of the pins and function of IC
