Overview
The Texas Instruments 5962-9686401QSA is a military-grade octal D-type edge-triggered flip-flop featuring three-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 utilizes a 20-pin Ceramic Flat Pack (CFP) package for through-hole mounting. Key electrical characteristics include a maximum propagation delay of 10.4 ns, with high-level output current capability of -50 mA and low-level output current of 50 mA. Static current consumption is specified at a maximum of 0.04 mA.
Feature Summary
- Octal configuration providing eight independent D-type edge-triggered flip-flops in a single package
- Three-state outputs enabling direct bus connections without external drivers
- Military-grade construction ensuring reliability across extreme temperature environments
Applications
- Military aerospace data processing systems
- High-reliability communication equipment
- Industrial control logic storage
Procurement Notes
Verify the specific suffix QSA against the manufacturer's official datasheet to confirm pinout compatibility and environmental ratings. Ensure the procurement channel provides valid traceability documentation required for military specifications. Confirm that the ceramic flat pack package matches the target board layout constraints before finalizing orders.
Selection Notes
Select this component when designing systems requiring high-density octal storage with bus-compatible outputs. The wide operating temperature range makes it suitable for harsh environments where standard commercial parts fail. Consider the 20-pin CFP footprint during PCB design to ensure adequate clearance and thermal management for the ceramic package.
Part Context
This part belongs to the SN54 series of high-performance logic devices manufactured by Texas Instruments. The SN54 family is distinguished by its extended temperature ranges and robust construction intended for defense and aerospace applications. It serves as a specialized variant of the commercial SN74 series, offering enhanced durability for critical infrastructure.
Replacement Considerations
The 5962-9686501QRA is a documented alternative octal D-type flip-flop with three-state outputs. Verify package compatibility between the CFP-20 and CDIP-20 formats before substitution.
