Thus spake Dave Mullenix (djmullen@FACSTAFF.WISC.EDU): > Faster, actually. Schottkey TTL is standard TTL, except that special > diodes (called, surprisingly enough, Schottkey diodes) are built into Just a little point, folks (and I apologize for being pedantic) - it's called Schottky (no 'e') and is named after Walter Schottky, a German physicist who invented the screen grid and tetrode vacuum tubes! He also described (in 1938) the behaviour of a metal-semiconductor junction that is the basis of the Schottky TTL we still use today. He died in 1976 at the age of 90. What an amazing life he must have had! Born in the steam age, lived to see the beginning of the microcomputer revolution. -- Clyde Smith-Stubbs | HI-TECH Software, | Voice: +61 7 3354 2411 clyde@htsoft.com | P.O.
