Differing editions give slightly different numbers. I was looking at the 1972
edition (which was the one that was closest to hand, no other reason); the
number I gave is on pg. 204. I haven't checked later ones to see if there
were further revisions.
The later 70mA sink spec is probably a slightly more robust number to work
with.
