Hi Guys:
This is a simple one. I've got a 0 to 5V square wave that I want to convert to a 0 to 3.3V square wave. I tried putting a series resistor and a 3.3V zener diode to ground.
The wave stays nice and square, but it comes out as 0 to 2.0 volts. I have tried varying the value of the resistor, but it doesn't help. What am I doing wrong? Is there a better way to do what I'm trying to do?
Thanks for any replies.
Don
