DUAL TERMINATOR RESISTOR VALUES – Schematic 5
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 suf fix l e t ter relates only to the sequence of vari ations that equal the sam e eq uivalent resistance.]
REQ = R1*R2/(R1 + R2)
768205131C R1 = 180 O hms R2 = 470 O hms REQ = 130 Ohms
Example
[Pin N/2 is common to R2 and Pin N is common to R1.]
