Overview
The SN54L122J/B is a monolithic integrated circuit manufactured by Rochester Electronics, LLC. It functions as a retriggerable one-shot multivibrator with a negative-edge trigger. The device is characterized for operation over the full military temperature range of -55°C to 125°C. It contains a single logic gate configured to generate precise output pulse widths determined by external timing components. The component utilizes a ceramic dual in-line package (CDIP) suitable for high-reliability applications.
Feature Summary
- Retriggerable one-shot multivibrator functionality
- Negative-edge triggering mechanism
- Military-grade temperature characterization
Applications
- Military aerospace systems
- High-reliability industrial control
- Precision timing circuits
Procurement Notes
Verify the specific suffix J/B against official manufacturer documentation to confirm package type and qualification level. Ensure compatibility with existing military specifications and environmental requirements before procurement. Confirm that the component meets all necessary reliability standards for the intended deployment environment.
Selection Notes
Select this component when a retriggerable one-shot with negative-edge triggering is required for military or high-reliability environments. Consider the fixed timing characteristics and external component requirements. Verify that the ceramic package and temperature range align with system constraints.
Part Context
This part belongs to the SN54L series of logic devices, which are designed for military specifications. Rochester Electronics provides lifecycle support for these legacy components, ensuring availability for long-term defense and aerospace programs where original equipment manufacturer supply may be discontinued.
Replacement Considerations
Check for direct pin-compatible replacements within the same family. Verify functional equivalence regarding trigger polarity and retriggering capabilities. Ensure any substitute meets the same military temperature and packaging requirements.
