i have looked through arduino, sparkfun and other source for information on "data sheets". i understand how helpful they can be when available. but it is the way it is explained that is...............uhm............they pick a product and tell you about stuff that doesn't pertain to what you are working on, though there is a lot of information. so if anyone has a few minutes i would like to get a more concise understanding of how to interpret a "data sheet" and i hope to be able to be "specific". knowledge of these parameters could be priceless in my estimation.

i would like to start with INPUT. specifically these items:

i have a date sheet. it tells me this:

input LOW voltage- sym Vil (0.8v) max

input HIGH voltage-sim Vih (2.0) min

output LOW voltage

output HIGH voltage

Vcc current (operating)

Vcc Current (standby)

input LEAKAGE current

input current HIGH

input current HIGH (not a typo)

output load Impedance

preamp input resistance

MIC sp +/- gAIN.

That's a lot and I don't expect anyone to have time for all of it. so would anyone like to take the first (2)?

OR.....point me to a page that can explain it since you have already been there. thanks
