- 2.0 and - 5.2 Volt ECL Terminator
The MDRC1641 circuit contains 11 resistors of nominally equal value and a
0.01 microfarad decoupling capacitor. The MDRC-1641 is designed for ECL Line
Termination to a - 2.0 volt buss. The 0.01 microfarad decoupling capacitor is for
bypassing transients between supply voltages.
The MDRC1642 circuit contains 12 resistors of 510 ohm each and a
0.01 microfarad decoupling capacitor. The MDRC-1642 is designed for ECL
Pull-down to a - 5.2 volt buss. The 0.01 microfarad decoupling capacitor is for
bypassing voltage transients on the voltage buss.

Thevenin Equivalent Terminator
The MDRC1643 contains four pair of series resistors. The circuit is compatible
with ECL pin configurations. Each terminator section (series pair) contains a
voltage divider between VCC (0 volt) and VEE (- 5.2 volt) providing a Thevenin
equivalent voltage of - 2.0 volts. A 0.01 microfarad decoupling capacitor
bypasses the VEE buss.
