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 770 part number includes the actual values of the

resistors in the dual terminator. For example:

770105180/470 R1=180Ω R2=470Ω

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.
