How are ICs named?
To me, ICs never have names that hint to their uses. For example, this AND gate from TI is named SN74LVC1G08. But that tells me nothing about what it does. Is there a naming process for ICs? And if so...

What's the peak voltage of the sawtooth generated by the ic SG3525 or UC3525?...
P.S. I need this information in order to make a closed-loop FlyBack CC-CC converter. The Tm transfer function is related to the sawtooth peak voltage: Thanks!

Strange IC input leakage current
I am reading the datasheet of the HEF4894BT. First I saw the input clamping current is rated at 10mA and than I saw the input leakage current would be 10mA, too. I thought the input clamping current is...
