5962-9314801QRA

Overview

The Texas Instruments 5962-9314801QRA is an octal edge-triggered D-type flip-flop with clock enable, belonging to the SN54ABT377 series. It features 3-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes ABT CMOS technology for high-speed performance. Key electrical parameters include a propagation delay of 10 ns at 5 V, with output drive capabilities of -12 mA (high) and 24 mA (low). It functions reliably across an extended temperature range from -55°C to +125°C and is housed in a 20-lead CDIP package.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops with edge-triggered operation synchronized by a common clock.
• Integrated clock enable input allows data storage control without affecting existing stored states when disabled.
• Three-state outputs facilitate direct bus connections, reducing external components in parallel data transmission systems.
• ABT CMOS technology ensures high-speed switching characteristics while maintaining low power consumption relative to bipolar alternatives.

Applications

• High-speed parallel data buffering in military communication systems
• Register files for aerospace computing architectures
• Data acquisition systems requiring precise timing synchronization
• Industrial control logic interfaces operating in extreme environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to military specification requirements. Confirm that the ordering suffix matches the exact pinout and electrical tolerances defined in the official datasheet. Request full traceability documentation including lot codes and material declarations to ensure compliance with defense industry standards. Validate package integrity upon receipt to prevent mechanical damage during handling.

Selection Notes

Select this component when system design demands high-speed octal latching with bus-compatible outputs in harsh thermal conditions. Compare propagation delays against system clock frequencies to ensure setup and hold time margins are met. Evaluate power dissipation limits within the enclosure to maintain junction temperatures within safe operating areas. Consider interface compatibility with upstream drivers and downstream loads to guarantee signal integrity across the entire data path.

Part Context

This part belongs to the SN54xx series, which denotes military-grade reliability and extended temperature ranges compared to commercial SN74xx variants. The 5962 prefix indicates it is a direct-read microelectronic device manufactured under government specifications. It serves as a radiation-hardened or high-reliability alternative to standard commercial logic families, ensuring consistent performance in critical applications where failure is not an option.

Replacement Considerations

SN54ABT377J: Commercial grade equivalent with identical pinout and functionality but limited to 0°C to 70°C operating range. Verify if environmental constraints allow substitution. Ensure voltage levels and output drive strengths remain compatible with existing circuit designs before implementing any cross-grade replacement.
