Admittedly, I do occasionally overlook the obvious, but in this case, I _did_
call TI about the CMOS 16R8 in SMT. I had to wait two days for someone to
call me back, then had to give the person on the other end of the phone line
a brief education on how CMOS PALs were different from bipolar and ECL PALs
(and were different from PROMs, etc).
I could have given the problem to our purchasing or component engineering
staff, but the problem resolved itself when I decided to pull the function in
question inside the gate array I was doing.
So, I remain ignorant on the availability of _small_ SMT CMOS PALs, and,
lacking an immediate requirement for them don't plan to try very hard to
rectify that. (Asking on the net is doesn't qualify as "very hard" :-)
