Where can I find the description of the comparator for the uPD789166?

Last Updated:12/26/2017


The uPD789166 Data Sheet has a description of the pin I/O circuits, and describes an N-ch open-drain output, and a 5V tolerant input buffer and comparator in type 13-X; but there is no description about the comparator.


This comparator is used only for the SMB interface of the uPD789166Y, to check whether the SMB input signal is over the threshold or not. 
Since the uPD789166 does not have an SMB interface, please ignore the description regarding the comparator.
