74LVQ74TTR

Overview

The 74LVQ74TTR is a dual D-type flip-flop manufactured by STMicroelectronics, belonging to the LVQ logic series. It features two independent 1-bit D-type flip-flops with positive-edge triggering in a TSSOP-14 surface-mount package. The device operates within a supply voltage range of 2 V to 3.6 V and supports industrial temperature ranges from -55°C to +125°C. Key electrical characteristics include low output drive current capabilities and propagation delays typical for low-voltage CMOS technology, ensuring reliable data storage and transfer in digital circuits.

Feature Summary

• Dual independent D-type flip-flop configuration for compact design
• Positive-edge clock triggering mechanism
• Low voltage CMOS operation compatible with 2V to 3.6V supplies
• Industrial temperature rating for robust environmental performance

Applications

• Digital data storage and latching circuits
• Synchronous state machines and counters
• Parallel-to-serial or serial-to-parallel conversion interfaces
• Timing delay elements in digital signal processing

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and specific tape-and-reel packaging requirements before ordering. Check lifecycle status as availability may vary across regions. Ensure proper ESD handling procedures during storage and assembly to maintain device integrity.

Selection Notes

Select this component when dual independent flip-flops are required in a small outline package. Consider the LVQ series for applications needing low voltage operation between 2V and 3.6V. Evaluate pin compatibility with existing PCB layouts using the TSSOP-14 footprint. Compare propagation delays and output drive strength against system timing requirements.

Part Context

This part belongs to the STMicroelectronics 74LVQ series of low-voltage quad logic devices. It complements other family members like the 74LVX594 shift register and 74LVX132 NAND gate. The series targets portable electronics and battery-powered systems requiring efficient power consumption and high-speed switching capabilities in standard logic form factors.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify logical equivalence for D-type flip-flop functionality. Ensure voltage levels and temperature ranges match original specifications. Consult official cross-reference lists for approved alternative part numbers.
