For high speed, PALs come in D (vu-vlsi == Villanova University) C'mon Phil, lighten up. Remember what it was like being in college? I don't remember bins of EPALS, Stag PAL programmers, or CUPL running on Sun workstations. I do remember protoboards, 74LS parts, programming EPROMS on an HP64000 and a TA that couldn't speak English. The only people my age (23) I know that used PALs in college as undergraduates went to Stanford. Without walking over to my bookcase, I have found the TI 74HCT238 in the high-speed CMOS databook. Don't know if you can find it in LS or ALS, but the HCT will work with LS parts. The 238 is like the 138 except the outputs are inverted. By the way, how does everyone like the new logic symbols? I like them, you can tell what a chip is doing without looking at the logic diagrams.
