DUAL TERMINATOR RESISTOR VALUES – Schematic 5
The Series 766 part number includes the EIA Code value of the Thevenin equivalent resistances of R

and R
2
. The Thevenin equivalent resistance is
calculated in the following way. [The suffix letter relates only to the sequence of variations that equal the same equivalent resistance.]
