This document serves as a technical specification sheet for the W590 series "IBM N Line to DEC Converter." The module features five inverting amplifiers designed to interface with three specific types of IBM line signals (N Transmission, C Line, and Logic).
Key details include:
- Operational Characteristics: Each amplifier has a nominal input impedance of 300 ohms, which can be adjusted to 100 ohms using 150-ohm shunts.
- Input/Output: The circuits include input biasing to ensure a stable output state when inputs are open-circuited. They are designed to tolerate input excursions up to +4V and -6V, allowing for potential compatibility with IBM T, D, or Q lines.
- Technical Specifications: The document provides specific voltage and current thresholds for different line types, as well as power requirements (+10V at 40mA and -15V at 23mA) and output capacity (18mA at ground, 1mA at -3V).
