74LVTH374MTCX

Overview

The 74LVTH374MTCX is an octal D-type flip-flop manufactured by Fairchild Semiconductor, now part of onsemi. It operates within a voltage range of 2.7V to 3.6V and features 3-state outputs. The device utilizes LVTH logic series technology for high-speed performance with low power consumption. It is housed in a 20-lead TSSOP package with a width of 4.4mm. Key electrical parameters include a propagation delay of 5.2ns, a high-level output current of -32mA, and a low-level output current of 64mA. The component supports single-ended inputs and outputs, with non-inverting polarity.

Feature Summary

• Octal D-type flip-flop architecture with 3-state outputs
• Compatible with 3.3V systems and 5V TTL interfaces
• Bus-holding capability eliminates need for external pull-up resistors
• Supports hot-switching operations during power transitions

Applications

• Bus-oriented memory applications
• Clock distribution networks
• High-speed data latching circuits
• General-purpose digital signal processing interfaces

Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor's logic division was acquired by onsemi. Ensure the ordering suffix matches the required tape-and-reel packaging configuration. Confirm RoHS compliance status and lead-free material specifications against the latest datasheet revision. Check for any obsolescence notices or production lifecycle changes that may affect long-term supply availability.

Selection Notes

Select this component when designing systems requiring 8-bit parallel data storage with tri-state bus control at 3.3V logic levels. The LVTH series offers improved noise immunity compared to standard LVT devices. Consider the 5.2ns propagation delay for timing-critical paths. Ensure the TSSOP-20 footprint aligns with PCB layout constraints and thermal requirements for surface-mount assembly processes.

Part Context

This device belongs to the 74LVTH family, which combines the speed of bipolar logic with CMOS low-power characteristics. It is functionally compatible with other 74-series logic standards while operating at lower voltages. The MTCX suffix indicates the specific TSSOP-20 package variant with reel packaging, distinguishing it from tube-packed or alternative package versions within the same logical family.

Replacement Considerations

Direct substitutes include the 74LVTH374 in alternative packages such as SOIC-20. Cross-reference with onsemi's current product portfolio for updated part numbers. Verify pinout compatibility before replacing with generic equivalents from other manufacturers.
