Overview
The SN54LS54 is a high-speed Low-power Schottky (LS) TTL logic integrated circuit manufactured by Rochester Electronics. It functions as a 4-wide AND-OR-Invert gate, performing the Boolean function Y = AB + CD + EF + GH. The device is characterized for operation over the full military temperature range of -55°C to 125°C. It utilizes a ceramic dual in-line package (CDIP) with 24 pins, ensuring reliability for demanding environments.
Feature Summary
- Provides four independent AND-OR-Invert logic gates within a single package
- Operates reliably across the full military temperature spectrum from -55°C to 125°C
- Constructed using Low-power Schottky TTL technology for enhanced performance
Applications
- Military avionics and defense systems requiring extended temperature tolerance
- Space-grade electronic equipment subject to harsh environmental conditions
- Industrial control logic circuits demanding high noise immunity
Procurement Notes
Verify that the component is sourced from an authorized distributor or qualified supplier list. Confirm the part number matches the specific 'BCA' suffix requirements. Ensure documentation includes original manufacturer test data or Rochester Electronics validation reports to guarantee compliance with MIL-PRF-38535 standards.
Selection Notes
Select this component when designing systems requiring robust logic gating under extreme thermal stress. The LS series offers a balance of speed and power consumption suitable for complex digital interfaces. Verify pin compatibility and package dimensions against existing board layouts before integration.
Part Context
Rochester Electronics specializes in providing lifecycle solutions for obsolete and hard-to-find semiconductors. This component is part of their extensive portfolio of recreated and original die parts, supporting industries that require long-term availability beyond standard commercial production cycles.
Replacement Considerations
Direct substitutes include other SN54LS54 variants from different manufacturers, provided they meet the same military temperature ratings and logical functionality. Cross-reference pinouts and electrical characteristics carefully to ensure seamless replacement.
