Schmitt Trigger

This document is a technical schematic diagram for the M503 Schmitt Trigger circuit, copyrighted in 1969 by Digital Equipment Corporation. The schematic details the transistor, diode, and integrated circuit configurations, along with their associated resistor and capacitor values, intended for test and maintenance purposes. It includes a transistor and diode conversion chart for referencing specific components like DEC3009B, 2N4250, and IN752A, and specifies operational parameters such as pin configurations for ICs (DEC7400N and MC1709C) and default component tolerances.
