[sdiy] Odd cmos chips?

[Dave Kendall]

Hi Dan.

 From the 1984 Motorola databook =  "CMOS DATA MANUAL VOLUME 1"

MC14566  = industrial Time-base generator - has a datasheet in the book 
with pinouts


MC14544  = BCD to 7-segment latch/decoder/driver with ripple blanking
MC14574 = Quad programmable comparator
MC14575 - programmable dual op-amp/dual comparator

These last 3 have no pinouts or data on the book, but simply have a 
note that says "See the CMOS Data manual, Volume 2, Special Functions." 
(which I don't have unfortunately)


cheers,
Dave
