Thanks for the link. Actually I am using Wenzel two transistors in my
other project. Works great. This time I tried to use LPRO-101. But that
one is to "square" outputs from MV89 OCXO. MCU like it.
I am wandering, if it can it be an issue, if I am using the same 74AC04
for all three purposes:
1. 1PPS to control the DAC
2. OCXO to feed the MCU
3. Input from DUT
