54LS183J

Overview

The 54LS183J is a dual full adder integrated circuit manufactured by Rochester Electronics, LLC. It belongs to the LS (Low-power Schottky) TTL logic series and features dual carry-save architecture. The device is housed in a CDIP-14 ceramic DIP package with glass-sealed construction. It supports operation across the full military temperature range of -55°C to 125°C. Key electrical parameters include a propagation delay of 15 ns and a maximum supply voltage of 5.5 V.

Feature Summary

• Dual full adder configuration providing independent arithmetic processing channels
• Carry-save architecture designed for high-speed digital computation applications
• Military-grade reliability ensured through ceramic packaging and extended temperature tolerance

Applications

• High-speed digital arithmetic logic units
• Military-grade computing systems requiring radiation-hardened or robust logic components
• Industrial control systems operating in extreme environmental conditions

Procurement Notes

Verify component authenticity against original manufacturer specifications. Confirm that the ceramic DIP-14 package matches system requirements. Ensure compatibility with existing TTL logic levels. Validate performance data against official datasheets before integration into critical circuits.

Selection Notes

Select this component when dual full adder functionality is required within a single package. Consider the LS series characteristics for balanced speed and power consumption. Verify that the military temperature range meets operational environment demands. Ensure pinout compatibility with legacy designs utilizing standard 54LS logic families.

Part Context

Rochester Electronics specializes in sourcing and manufacturing end-of-life semiconductors. This component represents a continuation of classic TTL logic families. The company ensures quality through ISO-9001 and AS9120 certifications. Parts are tested using original factory programs to guarantee specification compliance.

Replacement Considerations

Compatible substitutes include other 54LS183 variants from different manufacturers. Verify pinout and logical function equivalence before substitution. Ensure thermal and electrical ratings match original design constraints.
