pickit serial analyzer
I was browsing on the Microchip website and found they have a PICkit Serial Analyzer for sale and it can capture and analyse various serial bus signals.
I would like to build one by myself but I have a few questions (I have a PICkit2, so programming is not a problem - I hope):
https://ww1.microchip.com/downloads/en/DeviceDoc/51647B.pdf
For the FETs Q1, Q3 & Q5, they used IRLML6402 which is a P-channel MOSFET. Anyone can suggest some common FET to replace them? Because I read the datasheet for this and found out it has 0.065 Ohm of ON resistance and common P-channel FETs has like 8 Ohm IIRC.
D1 was ZHCS1000, which is a Schottky diode. Is there any more common part I can use instead? I am not sure what kind of Schottky diodes I can find in the hardware store --- all diodes I bought before was 1N4001, 4148 and Zeners.
Also, the MMBD4148 (D2), I can use a LL4148 to replace it, right?
Thanks!
