5962-9750801QFA

Overview

The Texas Instruments 5962-9750801QFA is a military-grade dual 2-line to 4-line decoder/demultiplexer belonging to the SN54LS155A series. It utilizes monolithic transistor-transistor-logic (TTL) technology and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a 16-pin Ceramic Flat Pack (CFP) package designed for surface mount installation. It supports an extended operating temperature range from -55°C to +125°C, ensuring reliability in harsh environments.

Feature Summary

• Dual independent decoding channels providing four outputs per channel
• Military qualification for extreme environmental stability
• Transistor-transistor-logic construction for robust signal integrity

Applications

• Military avionics data routing systems
• Spacecraft command and control logic
• Harsh environment industrial monitoring decoders

Procurement Notes

Verify the specific QDA or QFA suffix requirements against your design specifications, as these denote distinct packaging and testing standards. Confirm that the CFP-16 ceramic package aligns with your board layout constraints. Ensure procurement channels are authorized to handle restricted military components. Validate that the current revision matches your legacy system documentation to prevent integration errors during replacement.

Selection Notes

Select this component when dual independent decoding is required within a single package for space-constrained military applications. The LS TTL family offers a balance of speed and power consumption suitable for complex logic interfaces. Consider the CFP package for superior thermal dissipation and mechanical durability compared to plastic alternatives in high-vibration scenarios.

Part Context

This part is a militarized version of the commercial SN54LS155A decoder. It falls under the broader category of digital logic integrated circuits manufactured by Texas Instruments. The 5962 prefix indicates it is a direct-read military catalog item, distinguishing it from standard commercial logic families while maintaining functional compatibility with established TTL standards.

Replacement Considerations

Direct substitutes include other SN54LS155 variants with matching military suffixes. Verify pinout compatibility before replacing. Cross-reference with SN54S155 for faster switching if power budget allows.
