MC74VHC74DT

Flip Flops Overview

The MC74VHC74DT is a dual D-type flip-flop manufactured by onsemi, belonging to the VHC logic series. It features high-speed CMOS technology with a maximum propagation delay of 12 ns at 3.3V and 50pF load. The device operates within a supply voltage range of 2.0V to 5.5V, supporting both CMOS and TTL input compatibility. It includes asynchronous Set and Reset inputs for each flip-flop. The component is housed in a 14-pin TSSOP package, designed for surface-mount applications across an operating temperature range of -55°C to 125°C.

Flip Flops Feature Summary

• Dual D-type flip-flops with positive-edge clock triggering
• Asynchronous Set and Reset control inputs
• High-speed operation with low power consumption
• Wide supply voltage range supporting multiple logic families

Flip Flops Applications

• Parallel data storage and shift register circuits
• Timing delay elements in digital systems
• State machine implementation in embedded controllers
• Data synchronization between different clock domains

Flip Flops Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-14 package configuration required for your PCB layout. Confirm that the VHC logic family voltage levels align with your system's I/O requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your application's thermal conditions.

Flip Flops Selection Notes

Select this component when dual independent D-flip-flops are needed in a compact surface-mount package. The VHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Consider the 2.0V minimum supply voltage if designing low-power portable devices. Verify pinout compatibility if replacing legacy LS or HC equivalents in existing designs.

Flip Flops Part Context

This part belongs to onsemi's 74VHC series, which provides high-performance silicon-gate CMOS logic. The VHC line is designed to be pin-compatible with industry-standard 74LS and 74HC devices but offers improved speed and lower power dissipation. The MC74VHC74DT specifically implements the dual D-flip-flop function commonly used in sequential logic design.

Flip Flops Replacement Considerations

Direct substitutes include MC74VHC74D and MC74VHC74DR from onsemi, differing primarily in packaging or tape-and-reel options. Cross-manufacturer equivalents such as SN74VHC74DW from Texas Instruments may offer functional parity. Verify pinout and electrical characteristics before substitution.
