Dual Terminator Resistor Values
The Series 766 part number includes the EIA Code value of the Thevenin equivalent resistances of R1 and R2.
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. Reference Thevenin Equivalent Resistance
Chart.
