Dual Terminator Resistor Values & Codes
R2
Standard CTS Dual Terminator products contain (2N-2) resistors
of two different values with each resistor value connected to a
common buss. CTS assigns the resistance value portion of the
standard part numbers of the dual terminator network in two
different methods.

The Series 752, 766, 767 and 768 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 which equal the same equivalent resistance.
