Where are the 74ALS parts?

autodeskguest

I'm trying to find the following parts:

 

74ALS645D

74ALS08D

 

They don't seem to be in the default libraries nor in any downloadable

libraries I've found.

  • 74ALS645D is almost completely obsolete...you should use something else, or

    at least investigate a source before you commit & order boards (for parts

    that will never arrive).

     

    the non-D part is in stock in a few flavors

    Thanks for pointing this out. The project I want to do comes from a

    magazine from around 1987.

    Is the difference between the various types within a specific TTL part

    (i.e. all variations of the 74_645) to do with how much power it draws

    and package type? In other words, provided there's enough power

    available, all variations would work?
