5962-9759001QSA

Overview

The Texas Instruments 5962-9759001QSA is a military-grade octal edge-triggered D-type flip-flop with 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to +125°C. The device is housed in a 20-lead Ceramic Flat Pack (CFP) package. It belongs to the SN54F series, utilizing bipolar logic technology.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Edge-triggered data latching mechanism for precise timing control
• Three-state output capability allowing bus line driving and isolation
• Military qualification ensuring reliability under extreme environmental conditions

Applications

• High-reliability aerospace computing systems
• Military communication equipment data registers
• Harsh environment industrial control logic storage
• Defense radar signal processing memory elements

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and screening level. Confirm that the component meets MIL-PRF-38535 Class Q standards if specified for your application. Ensure compatibility with existing board layouts due to the ceramic flat pack dimensions. Check for any recent product lifecycle notices regarding availability or obsolescence before finalizing procurement plans.

Selection Notes

Select this component when high-speed octal data storage is required in environments exceeding commercial temperature limits. The 3-state outputs facilitate efficient bus architecture designs. Consider the CFP package size constraints during mechanical design. Verify power supply stability within the 4.5 V to 5.5 V range to ensure proper logic threshold operation across the full temperature spectrum.

Part Context

This part is a mil-aero version of the SN54F374 octal D-flip-flop. It shares functional similarities with other SN54F series devices but offers enhanced ruggedness. It serves as a critical memory element in digital logic circuits requiring robust performance. The ceramic packaging provides superior thermal and mechanical stability compared to plastic alternatives.

Replacement Considerations

Direct substitutes include other mil-aero qualified SN54F374 variants with compatible suffixes. Cross-reference pinouts and electrical specifications carefully. Ensure that any replacement maintains the same 3-state output functionality and voltage requirements.
