M362

This document is a schematic diagram for a "LATCHED REGISTER DRIVER M362" circuit, created by Digital Equipment Corporation in 1971.

Key features of the document include:

• Purpose: It is explicitly stated as being for test and maintenance purposes, and the circuits are proprietary.
• Circuit Details: The schematic illustrates a digital circuit incorporating various components such as integrated circuits (specifically DEC1074H53 and DEC1074H00), transistors (2N4258, 3009 B-S, DEC4258), diodes (FD777, D662), resistors, capacitors, and delay lines.
• Parts List: A detailed table enumerates all components by DEC Part Number, Description, and Quantity, including various resistor, capacitor, diode, transistor, and IC types, as well as an etched circuit board and assembly/drilling hole layout information.
• Component Specifications: General notes provide default specifications for resistors (1/4W, 5%), capacitors (0.01uF, 100V, 20%), and common diode and transistor types. It also specifies IC pin assignments (Pin 7 = GND, Pin 14 = +5V).
• Conversion Chart: A "Transistor & Diode Conversion Chart" provides equivalent EIA part numbers for DEC components.
• Revision Information: The document is identified as Revision C.
