I'm worried now that TI is the only one making the CD40109 that soon they will quit too. It's a low-to-high voltage translator and being old-style CMOS it works from 3 to 15 volts. So I'm looking for equivalents. Don't need great power or speed. But I do need 3.3 volts on the input and at least 8 volts on the output side.
