Pin numbers are for all packages except the PW and FK package. RESET can override TRIG, which can override THRES (when CONT pin is 2/3 VDD).
The resistance of “R" resistors vary with VDD and temperature. The resistors match each other very well across VDD and temperature for a temperature stable control voltage ratio.
