CTS Dual Terminator Schematics
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.
Reference chart.
Req = R1R2
(R1 + R2)
Examples:
766165131A
R1=220Ω
R2=330Ω
Req=132Ω
767145191A
R1=330Ω
R2=470Ω
Req=194Ω
768205131C
R1=180Ω
R2=470Ω
Req=130Ω
Pin N/2 is common to R2 and Pin #N is common to R1 on
CTS Series 766, 767 and 768 .
Pin #1 is common to R2 and Pin N is common to R1 on all
CTS Series 752, 753 and 770 dual terminator schematics.
1. All tolerances ±2%.
2. Other values available on request.
3. Suffix letter has no significance–assigned in sequential order.
