That is very clever. You guys are so good at routing!

That is so brilliant, thank you! I like this solution cause then one can use common parts which are much readily available.

Inverting Buffer, awkard legacy layout
When I first checked the link, I saw the SN74HC244 buffer with inputs and outputs crossing from left to right. Upon further inspection I see it also has the SN74HC240....

Didn't know you get bipolar buffers, those are pretty neat!

This is the best routing I could think of (needs lots of vias though):   For future people, manage to find this part: SN74HC240

I agree  TBD62783A  is not good for digital system, was just an example of an easy to user layout. Been trying to make the 74HC4049 but can't make it neat.   That...

HA-5002 Unity gain buffer but doubles the output Voltage?
Hi,   In the datasheet there are other examples where the gain was really 1 and I couldn't reconcile why sometimes it seems amplified, and sometimes it is not.  ...

HA-5002 Unity gain buffer but doubles the output Voltage?
Hi Jim, thanks for your reply, it is a great help. Okay so that makes a bit more sense.   So for my circuit I simulated, if I actually built it, wou are saying I see Vout=...

Fast Transistor Switching using Cascode configuration
Thanks for the reply, ah yes the base resistor helped a lot! However a capacitor on Q3 base to GND acts like a smoothing cap and slows things down.

Run an inductor twice current if half the duty cycle?
Kartman, omw! You have always given me helpful advice. I remember asking about making PLC like IO for a MCU about 8 years ago and you gave me brilliant advice that really helped...

Thanks Jim you legend! I will see if I can find more specs on the inductor and deduce something intelligent.
