SNJ54HC09FK

Inverter Gates Overview

The SNJ54HC09FK is a military-grade logic component manufactured by Texas Instruments. It belongs to the HC/UH series and functions as a quad 2-input positive AND gate with open-drain outputs. The device is housed in a 20-lead Ceramic Quad Flat Package (CQCC20), also designated as LCC20. It operates within an extended temperature range of -55°C to 125°C, ensuring reliability in harsh environments.

Inverter Gates Feature Summary

• Quad 2-input positive AND gate configuration
• Open-drain output structure for wired-AND capability
• Military-grade qualification for extreme conditions
• Ceramic hermetic packaging for environmental protection

Inverter Gates Applications

• Military avionics systems
• Spacecraft digital logic circuits
• Harsh environment industrial control
• High-reliability communication equipment

Inverter Gates Procurement Notes

Verify the manufacturer's datasheet for specific electrical characteristics and mechanical drawings. Confirm that the CQCC20 package requires specialized surface-mount or ceramic socket handling. Ensure supply chain sources provide traceability documentation required for military and aerospace procurement standards.

Inverter Gates Selection Notes

Select this part when open-drain AND logic is required in high-reliability applications. The HC technology offers CMOS compatibility while maintaining military temperature ratings. Verify external pull-up requirements due to the open-drain output nature. Compare against standard commercial grades if environmental exposure is not severe.

Inverter Gates Part Context

This component is part of the SNJ54 family, which denotes Texas Instruments' military-grade semiconductor line. The 'HC' suffix indicates High-speed CMOS technology, offering lower power consumption than older TTL families. The 'FK' suffix specifies the ceramic flat package variant suitable for radiation-hardened or high-vibration applications.

Inverter Gates Replacement Considerations

Direct replacements include other military-grade quad 2-input AND gates with open-drain outputs in CQCC20 packages. Verify pinout compatibility and electrical specifications against equivalents from authorized distributors. Cross-reference with SN54HC09 variants only if commercial grade suffices.
