74LVX374TTR

Overview

The 74LVX374TTR is an octal D-type flip-flop with 3-state non-inverting outputs, manufactured by STMicroelectronics. It operates within a supply voltage range of 2 V to 3.6 V and features low-voltage CMOS technology. The device includes 5 V tolerant inputs, allowing compatibility with mixed-voltage systems. Propagation delays are specified at 14 ns and 12.5 ns under standard conditions. It is housed in a TSSOP-16 surface-mount package and supports serial-to-serial/parallel counting sequences. The component is designed for industrial temperature ranges from -55°C to +125°C.

Feature Summary

• Octal D-type flip-flop architecture with 3-state non-inverting outputs
• Low-voltage CMOS fabrication with sub-micron silicon gate technology
• 5 V tolerant inputs for mixed-voltage system integration
• Industrial temperature rating supporting wide operational environments

Applications

• Data storage and buffering in digital logic circuits
• Interface bridging between low-voltage and 5 V logic domains
• Parallel data acquisition systems requiring tri-state control
• High-speed sequential logic applications in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the prevalence of counterfeit integrated circuits in the market. Confirm RoHS compliance status and specific manufacturing lot codes against current datasheet revisions before integration. Ensure that the TSSOP-16 package dimensions match the target PCB footprint requirements precisely. Check for any obsolescence notices or lifecycle changes that may impact long-term supply chain stability.

Selection Notes

Select this component when designing systems requiring octal storage with high noise immunity and mixed-voltage input tolerance. The LVX series offers superior performance compared to standard LV/LVC families regarding speed and power consumption at low voltages. Consider the 3-state output capability if bus sharing or multi-driver configurations are necessary. Evaluate thermal management needs given the extended operating temperature range up to 125°C for robust industrial reliability.

Part Context

This part belongs to the 74LVX family of low-voltage CMOS logic devices, which are optimized for portable and battery-powered applications. The 74LVX374 specifically provides octal storage functionality, distinguishing it from simpler gates or decoders within the same logical hierarchy. It complements other LVX components like shift registers and buffers to form complete digital signal processing chains in modern electronic designs.

Replacement Considerations

Direct substitutes include the 74LVC374 variants from manufacturers such as Texas Instruments or Nexperia, provided voltage levels and pinouts are compatible. Cross-reference functional equivalents from onsemi or NXP, ensuring that propagation delay specifications meet the original design constraints. Verify that alternative packages maintain the same electrical characteristics and thermal performance profiles.
