I think what they meant was that the 16C74 has been superseded by the
16C74A. Ask them for a 16c74A and see if that helps.

If you get a 16C74A remember the following:

The 16c74A is slightly different from the 16C74. For starters, the 16C74A
code protection cannot be erased so don't program it. (Please! don't let
this start other thread on the subject!) The PWRTE bit is reversed on the
16C74A and the 16C74A adds a brownout circuit controlled with the "BODEN"
bit in the config word.

Just make sure you use the .INC file for the 16C74A and don't use code
protection and you should be ok.
