M119

This document is a schematic diagram titled "3-8 INPUT NAND-GATES M119" from Digital Equipment Corporation, dated August 1967.

The schematic illustrates three identical 8-input NAND gates (E1, E2, E3), each with specific input and output pins identified. It includes notes specifying that Pin 7 on each integrated circuit (IC) is connected to ground (GND) and Pin 14 to +5V.

A separate section of the circuit features a resistive network (R1, R2, R3, R4) with input/output points UI and V1, and three decoupling capacitors (C1, C2, C3) connected between +5V and ground.

A parts list details the components:

• E1 through E3: Integrated Circuit DEC7430N (Part No. 1905578).
• R1 & R3: 750 Ohm, 1/4W, 5% CC Resistors (Part No. 1301401).
• R2 & R4: 330 Ohm, 1/4W, 10% CC Resistors (Part No. 1300293).
• C1 through C3: 0.01MFD, 100V, 20% DISC Capacitors (Part No. 1001610).
