[sdiy] TLC272 vs CA3140

[Jay Schwichtenberg]

Another thing to look out for is the supply voltage. A lot of the TLC and
TLV parts won't work with 30 volts(+-15 volts) usually because they were
designed for low power applications. After looking at the data sheet the
TLC272 it's one of those, only good for 16 volts. Don't know if that work
work for you or not.
