Hello,
Could someone provide me a circuit diagram to make the CD40109B (or equivalent chip) level shifter to shift a 3.3V data signal to roughly 20 volts (15-20 V boost would be okay)? I need to boost the data signal to drive it down a very long data transmission line. I have read the technical datasheet on this chip but it is not very helpful for examples. My data transmission speed is 115200 bps. Thanks for any help I can get.
