25LSxxx =? 74LSxxx

[skippy1729]

I am working with and old schematic with parts like: 25LS08, 25LS138, 25LS151, 25LS157, 25LS158, 25LS253. Am I correct in assuming that these are functionally and electrically equivalent to the corresponding 74LS*** parts?

All of these 25LS parts were originally manufactured by Advanced Micro Devices.

Thanks for any help. Skippy
