Re: PIC16F1508 ESD Protection for EUSART
Switching speed and lower voltage drop. But they have more leakage. There are always tradeoffs. I don't have a model for a TVS diode, but it looks like it might not be needed, although it wouldn't hurt. Simulations go only so far - it would be interesting to do testing on actual hardware. But it would require specialized and expensive equipment to do properly.
