This document provides the technical test specifications and a schematic diagram for the R151 Binary to Octal Decoder flip-chip module.
Summary of Contents:
- Test Specifications: The document outlines key operational parameters for the module, including load test current limits (1.8 mA to 2.2 mA), voltage levels (3.2 V to 3.9 V), output saturation voltage ($V_{CE}$), and total transition times for rise (70 ns) and fall (300 ns). It also includes a maintenance requirement to check for shorts between terminals C and D.
- Maintenance Guidelines: Recommendations for repairing printed circuitry are provided, emphasizing the use of low-voltage, cool soldering irons to protect copper and transistors, as well as the necessity of grounding oscilloscopes to avoid damaging transients.
- Schematic Diagram: The document includes a detailed circuit diagram (RS-B-R151) displaying the arrangement of transistors, diodes, and resistors, along with a transistor and diode conversion chart for maintenance reference.
