@bubu not sure what you're making, but if you have the space for it, a socketed 75176 gives you lots of choice of drive chips with different slew rates for experimentation / replacement if problems arise.
 
I see, I am building a 4 axis CNC motion controller. Even though space is less and most components are SMD. But since its a prototype board maybe sockets might be a good way to approach this.
 
Just a comment: I have a lot of RS484, mostly Modbus and DMX, and regularly see blown buffer chips on otherwise undamaged boards ... so we try always to get socketed drivers
Obviously I meant RS485

For your work, is there a certain name or type of document that details why certain components were chosen for a design?
This 1.5 A LED driver is used in a design. Although, it's past end of life. The only 1.5 A replacement I searched is a non-standard part with a lead time of two years...

Ok, well the engineer that designed it just said it was selected because that's what the LED specs allowed :)

Like a design intent document?
