Hi all,
My reacquaintance with Nixie's is progressing well and I'm looking at
experimenting with driving them via a Raspberry Pi. I know this is complete
overkill but it makes for a nice experimentation platform and I'm comfortable
with Python (so eases the learning curve!).
With this in mind and given the Pi's low GPIO pin count, I want to experiment
with shift registers and I believe that the 74HCT595 is suitable for driving
via from the Pi's 3.3v logic. However, I'm having difficulty finding this chip
in a DIP package.
Does anyone know of a source of these shift registers in DIP form (or indeed
any equivalents)?
Many thanks
Matt
Matt,
You will do much better searching for the 74HC595 rather than the
74HCT595. It has different (CMOS) input threshold voltage, but it's
widely available in DIP for much less money.
