54H52J/C

Overview

The Rochester Electronics 54H52J/C is a hermetically sealed ceramic DIP-14 AND-OR gate. It belongs to the TTL/H/L series and features a 9-input configuration with expandable inputs. The device utilizes a center pin for VCC and GND connections within its glass-sealed ceramic package. It operates across a temperature range of -55 °C to +125 °C. This component is designed for high-reliability applications requiring radiation hardness and stable performance in harsh environments.

Feature Summary

• Hermetically sealed ceramic DIP-14 package (CDFP14) with glass sealing
• TTL/H/L series logic with 9-input AND-OR function
• Expandable input capability for circuit expansion
• Center pin configuration for VCC and GND connections
• Wide operating temperature range from -55 °C to +125 °C

Applications

• Aerospace and defense systems requiring radiation-hardened logic
• Military equipment operating in extreme environmental conditions
• High-reliability industrial control systems
• Spacecraft avionics and satellite communication subsystems

Procurement Notes

Verify the specific manufacturing lot and date code upon order confirmation, as Rochester Electronics sources components from various original manufacturers. Confirm that the ceramic hermetic seal integrity meets project requirements. Ensure compatibility with existing PCB footprints for CDFP14 packages. Request detailed test reports if radiation hardness certification is mandatory for the application.

Selection Notes

Select this component when a hermetically sealed AND-OR gate with 9 inputs is required for high-reliability environments. Compare against standard plastic-packaged alternatives if radiation tolerance or long-term stability in vacuum/temperature extremes is critical. Verify voltage levels match the TTL/H/L series specifications for the target system logic family.

Part Context

Rochester Electronics specializes in providing lifecycle support for obsolete and hard-to-find semiconductors. The 54H52J/C is part of their portfolio of military-grade and space-qualified logic devices. These components are often sourced from original manufacturer inventory or manufactured using archived processes to maintain availability for legacy aerospace and defense programs.

Replacement Considerations

Direct replacements must be hermetically sealed ceramic DIP-14 AND-OR gates from the 54H52 series. Verify pinout compatibility, specifically the center pin power/ground configuration. Check if alternative suppliers offer equivalent radiation hardness ratings and temperature ranges.
