The first logic I studied was RTL (resistor/transistor/logic) which If I recall correctly ran at 3.6 VDC. So what what's new is old. Seems that Don Lancaster has posted the book I started on my logic journey:http://www.tinaja.com/ebooks/RTLcb.pdfLefty
I think I was browsing wikipedia when I first read about it (the way it seems to be kept hush on, its like the ugly step-brother to TTL who's locked in the attic or something).
QuoteI think I was browsing wikipedia when I first read about it (the way it seems to be kept hush on, its like the ugly step-brother to TTL who's locked in the attic or something).Not ugly, just a short life run as the advancement from RTL to DTL (diode/transistor/logic) to TTL happened in over such a few short years. Once all the advantages of TTL were understood it became the dominate logic for a long time until various CMOS logic favors came along.
Just curious about this. Does anyone have a perspective on why the stock Arduino boards are 5v instead of 3.3? It seems like it would have simplified much with peripherals.
