I'm pretty new to electronics, and this question is probably pretty simple, I'd imagine.
On any TTL chip, I believe the supply voltage for the chip itself is 5V and the supply current is 20mA. Also, the supply voltage for a "high" is 5V and 0-.8V for a "low", I think. How much current is too much for TTL inputs, as in, how much until it fries? How much is too little?
Like I said I'm pretty new to all this, so thanks for your patience.
