M312 Delay Lines

The M312 module features six delay lines, five of which are fixed (with a ±5% tolerance) and one of which is variable (0–40 ns). Input NAND gates for these lines add a further 10 ns of delay. The document outlines specific pin assignments, provides a simplified circuit diagram, and details the electrical characteristics, including input loading (1.25 TTL unit loads), maximum output drive capabilities for each delay line type, and a maximum power dissipation of 5V at 275 mA.
