Overview
The 54H11W/R is a high-reliability triple 3-input AND gate manufactured by Rochester Electronics, LLC. It belongs to the SN54Hxx series of High-Speed TTL logic devices. The component utilizes hermetic ceramic flatpack packaging to ensure environmental stability. It is designed for operation across the military temperature range of -55°C to +125°C. The device provides three independent AND gates within a single package.
Feature Summary
- Hermetic ceramic flatpack construction for radiation and harsh environment resistance
- High-speed TTL logic family performance characteristics
- Triple 3-input AND gate functionality
- Qualified for extended military temperature ranges
Applications
- Aerospace computing systems
- Military communication equipment
- Spacecraft logic circuits
- Harsh environment industrial control
Procurement Notes
Verify the specific revision level and lot traceability documentation upon procurement. Confirm that the hermetic seal integrity meets MIL-STD-883 requirements for your application. Ensure compatibility with existing board layouts regarding the flatpack pinout dimensions. Request test reports verifying radiation hardness levels if operating in space environments.
Selection Notes
Select this component when standard commercial logic fails under extreme thermal or radiative conditions. The hermetic package distinguishes it from plastic-packaged equivalents. Consider the power dissipation limits inherent to the H-TTL family. Verify that the 3-input gate density matches the circuit design requirements without excessive fan-out limitations.
Part Context
Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find components. This part is a continuation of the Texas Instruments SN54H11 lineage. It serves legacy defense and aerospace systems requiring proven reliability. The 'W' suffix typically denotes the ceramic flatpack variant.
Replacement Considerations
Direct replacements include the original Texas Instruments SN54H11W. Equivalent parts from other manufacturers must match the hermetic ceramic package and H-TTL electrical specifications. Verify pin compatibility before substitution.
