5962-9685601QSA

Overview

The Texas Instruments 5962-9685601QSA is an octal transparent D-type latch featuring three-state outputs, belonging to the SN54AHC573 series. It operates within a supply voltage range of 2 V to 5.5 V and supports through-hole mounting in a 20-pin Ceramic Flat Package (CFP). The device functions across an extended industrial temperature range from -55°C to +125°C. Designed for high-speed digital applications, it provides eight independent latches with TTL-compatible inputs and CMOS logic characteristics.

Feature Summary

• Octal configuration providing eight independent transparent D-type latches
• Three-state outputs enabling direct bus driving capabilities
• Wide operating voltage range supporting 2 V to 5.5 V systems
• Extended temperature rating suitable for harsh military environments

Applications

• Military aerospace data acquisition systems
• High-reliability telecommunications equipment
• Industrial control system memory buffers
• Automated test and measurement instrumentation

Procurement Notes

Verify the specific QRA or QSA suffix requirements against your bill of materials, as these denote distinct qualification levels and packaging variations. Confirm that the 20-pin CFP package dimensions align with your PCB footprint constraints. Ensure that the component's radiation hardness and reliability standards meet your program's specific military or spaceflight certification requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring octal latching with bus-oriented three-state outputs in rugged environments. The AHC technology offers superior speed-power product compared to standard HC devices. Consider the CFP package for its thermal stability and mechanical robustness in vibration-prone applications. Verify input compatibility with existing TTL logic families to ensure seamless integration without additional level shifting circuitry.

Part Context

This part belongs to the SN54 series, which denotes military-grade performance and extended temperature ranges compared to commercial SN74 variants. The 5962 prefix indicates it is a direct chip buy item manufactured under DoD specifications. It serves as a high-reliability alternative to commercial logic latches, ensuring consistent performance in defense and aerospace applications where standard commercial components are unsuitable.

Replacement Considerations

Direct equivalents include other SN54AHC573 variants with compatible suffixes. Verify pinout compatibility when substituting with generic SN54AHC573 parts. Ensure replacement packages match the 20-CFP form factor. Cross-reference radiation tolerance specifications if the application involves nuclear or high-altitude environments.
