74LCX16374MTD

Overview

The Fairchild Semiconductor 74LCX16374MTD is a dual 8-bit D-type flip-flop integrated circuit designed for high-speed digital applications. It operates within a supply voltage range of 2V to 3.6V, ensuring compatibility with low-voltage logic systems. The device features positive-edge triggering and provides three-state non-inverting outputs, allowing for effective bus management in parallel data transmission scenarios. With a maximum propagation delay of 6.2ns at 3.3V and a clock frequency capability of 170MHz, it supports rapid signal processing. The unit is housed in a 48-TFSOP package, suitable for surface-mount assembly, and maintains a static current consumption of only 20µA.

Feature Summary

• Dual 8-bit architecture providing two independent sets of D-type flip-flops for efficient data storage
• Positive-edge triggered operation synchronized with the rising edge of the clock signal
• Three-state non-inverting output configuration enabling direct connection to system buses
• Low power dissipation characteristics with minimal static current draw during operation

Applications

• Parallel data storage and transfer in communication interfaces
• Bus-oriented applications requiring byte-controlled data latching
• High-speed digital signal processing circuits
• Memory interface modules for portable electronic devices

Procurement Notes

Verify that the ordered component matches the exact part number 74LCX16374MTD to ensure correct package type and electrical specifications. Confirm compliance with RoHS3 standards and check the moisture sensitivity level (MSL 2) requirements for proper handling and storage conditions prior to soldering. Ensure the supplier provides valid datasheets and material declarations for regulatory adherence.

Selection Notes

Select this component when designing systems requiring dual 8-bit registers with high-speed performance under low voltage conditions. The 170MHz clock frequency and 6.2ns propagation delay make it suitable for demanding timing constraints. Consider the 48-TFSOP package dimensions for PCB layout compatibility and verify that the 2V-3.6V operating range aligns with the target system's power supply architecture.

Part Context

This device belongs to the 74LCX series of CMOS logic components, which are optimized for low voltage operation while maintaining high speed. As a member of the 74LCX16374 family, it shares functional similarities with other octal flip-flops but offers a dual configuration. The manufacturer onsemi continues production of this part, indicating its relevance in modern embedded designs despite the original Fairchild Semiconductor branding history.

Replacement Considerations

Cross-reference with equivalent parts from other manufacturers offering identical pinouts and electrical parameters. Verify that any substitute component supports the same 48-TFSOP package and 2V-3.6V supply range. Ensure the replacement maintains the 170MHz clock frequency and 6.2ns propagation delay specifications to avoid timing violations in existing circuit designs.
