Dual Terminator Resistor Values
The Series 766, 767, 768 part numbers include 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 chart.
Req=R1R2/(R1 + R2)
Examples:
766165131A R1=220 Ohms R2=330 Ohms Req=132 Ohms
767145191A R1=330 Ohms R2=470 Ohms Req=194 Ohms
768205131C R1=180 Ohms R2=470 Ohms Req=130 Ohms
Pin N/2 is common to R2 and Pin #N is common to R1 on CTS Series 766, 767 and 768.
