Overview
The Rochester Electronics 54H71DM is a high-speed ECL AND-OR-Invert gate belonging to the 54H series. It features a ceramic DIP-14 package with glass-sealed construction for military-grade reliability. The device operates on dual power supplies, typically ±5V, supporting a maximum operating temperature of 125°C and a minimum of -55°C. Key electrical parameters include a propagation delay of 0.6 ns and a typical power dissipation of 38 mW per gate.
Feature Summary
- High-speed ECL logic architecture optimized for rapid switching applications
- Robust ceramic DIP-14 package designed for harsh environmental conditions
- Dual power supply operation ensuring stable performance in critical systems
Applications
- Military avionics control units
- High-frequency signal processing circuits
- Radar system timing logic
Procurement Notes
Verify the specific manufacturer date code and lot traceability upon receipt, as Rochester Electronics sources components from various original manufacturers. Confirm that the ceramic package integrity matches the required MIL-STD specifications for your application environment. Request detailed test reports to ensure the propagation delay and power consumption remain within the documented datasheet limits for the 54H series.
Selection Notes
Select this component when extreme speed and radiation hardness are prioritized over low power consumption. The ECL technology offers superior transition times compared to TTL or CMOS alternatives but requires careful attention to impedance matching and termination resistors. Ensure your design accommodates the necessary negative voltage supply rails and thermal management for the ceramic package.
Part Context
This part belongs to the standard 54-series military logic family, known for strict manufacturing tolerances and extended temperature ranges. The 54H variant specifically denotes high-speed ECL performance. Rochester Electronics provides these legacy components to support long-term maintenance and production runs where original OEM availability has ceased.
Replacement Considerations
Direct pin-compatible replacements may include other 54H71 variants from different manufacturers, such as those from Texas Instruments or Signetics, provided they meet the same ECL voltage and speed specifications. Verify that any substitute maintains the identical ceramic DIP-14 footprint and glass-seal quality.
