The
semi-0discrete solution ('74 as a divide by 2 and a handful of
transistors) turns up all over the place. It's easy to design and reliable.
Always nice to know. I just need to figure out how much write current

doesn't include any figures or calculations, just a pinout and a few
electrical specs).
