Hello,
If the digital output (LVCMOS 3V3) is heavily loaded , we may need to use buffer to meet Vih & Ioh (output high current) level of the receiver circuit.
I prefer not use the stand-alone Buffer IC's . Can anyone guide me to design my own buffer circuit based on Transistors ??
Thanks
Antony

In spite of having used the above, several times in the past with no issues, today, after replacing in a working design, the 18F452 in charge with a 18F4431, I found the keyboard and LCD, not responding. After much RTFM, I noted that pins
RB0 / PWM0
RB1 / PWM1
RB2 /...
