what 100k

hi,
I know the specifications for the ECL10K and ECL100K level.But I do not know what the 10K or 100K mean? Anyone pls. tell me what the "100K"stands for?

Thanks
 

It stands for the chip logic family. Originally, the 10k family chip numbers were assigned with 5 digits (i.e. 10xxx, 101xx, etc). When the faster logic famliy was developed, the chip numbers were assigned 6 digits (i.e. 100xxx, 101xxx, etc.), to differentiate them from the earlier slower chips.

The 100K series, in addition to being faster, had improved features such as temperature and voltage compensation.

These have band gap references inside. They make a cheap way to make reference signal levels for self calibration.
