Overview
The SN54HC4002J is a military-grade dual 4-input NOR gate manufactured by Texas Instruments. It operates within the HC/UH logic series and features standard input conditioning. The device is housed in a 16-pin Ceramic Dual In-Line Package (CDIP) with a lead length of 0.3 inches. It supports a load capacitance of 50 pF and provides a maximum low-level output current of 5.2 mA. The component is rated for an extended temperature range from -55°C to +125°C, ensuring reliability in harsh environments.
Feature Summary
- Military-grade qualification for high-reliability applications
- Dual independent four-input NOR logic functions
- Robust ceramic packaging for extreme environmental stability
Applications
- Aerospace computing systems
- Military communication equipment
- Harsh environment industrial control
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with existing board layouts requiring ceramic DIP packages. Confirm supply chain authenticity through authorized channels due to military grade status.
Selection Notes
Select this component when military reliability standards are mandatory. The HC series offers CMOS power efficiency compared to older TTL counterparts. Verify voltage requirements align with system design limits before integration into critical circuits.
Part Context
This part belongs to the SN54HC family, designed for high-speed digital applications. Unlike commercial variants, the SN54 prefix indicates qualification for military specifications. The HC technology ensures low power consumption while maintaining fast switching speeds suitable for complex logic operations.
Replacement Considerations
Direct substitutes include other SN54HC4002 variants with compatible pinouts. Verify that alternative components meet the same military temperature and radiation hardness requirements. Check package dimensions to ensure mechanical fit within the assembly.
