G766

This document is an electrical schematic and associated documentation for a "LEVEL TERMINATOR" circuit, developed by Digital Equipment Corporation and dated April 1972 (drawing number G766-0-1).

The circuit primarily consists of numerous diodes (D662 and D664 types), resistors (various values including 7.5KΩ, 1.5KΩ, and 47Ω), and capacitors (0.1μF 100V DISC). It operates with multiple voltage rails, including -0.7V, -2.8V, -15V, and Ground, and interfaces via a 40-pin J1 connector, suggesting its role in terminating multiple signal lines to specific voltage levels.

General specifications state that all resistors are 1/4W 5%, all capacitors are 0.1μF 100V 20% DISC, and specific diodes (D11 through D38) are D664.

The document also includes a Parts List detailing the quantities, reference designations, descriptions, and part numbers for components (jumpers, resistors, connector, diodes, capacitors), along with references to related manufacturing documents like the etched circuit board, module history, and layout information. A proprietary notice from Digital Equipment Corporation is present.
