MM74HC374MTC

Flip Flops Overview

The MM74HC374MTC is a high-speed octal D-type flip-flop manufactured by Fairchild Semiconductor. It utilizes advanced silicon-gate CMOS technology to provide high noise immunity and low power consumption. The device features 3-STATE outputs, making it suitable for interfacing with bus lines in bus-oriented systems. It operates within a wide voltage range of 2V to 6V and can drive up to 15 LS-TTL loads. The component is housed in a 20-pin TSSOP package.

Flip Flops Feature Summary

• Advanced silicon-gate CMOS technology ensures high noise immunity and low power dissipation.
• Octal configuration provides eight D-type flip-flops with positive edge triggering.
• Three-state outputs facilitate direct connection to system buses without additional drivers.
• Compatible with standard TTL logic loads, allowing easy integration into mixed-logic designs.

Flip Flops Applications

• Bus-oriented systems requiring data storage and transfer.
• Interfacing between microprocessors and peripheral devices.
• General-purpose memory applications involving parallel data latching.
• Digital signal processing circuits requiring edge-triggered storage elements.

Flip Flops Procurement Notes

Verify the manufacturer marking on the component body to confirm Fairchild Semiconductor origin. Ensure the package matches the specified 20-lead Thin Shrink Small Outline Package (TSSOP) dimensions. Check for RoHS compliance documentation if environmental regulations apply to your assembly process. Confirm that the suffix 'MTC' corresponds to the tape-and-reel or tube packaging format required for your manufacturing line.

Flip Flops Selection Notes

Select this component when an octal flip-flop with three-state outputs is required for bus interfacing. It is appropriate for designs needing compatibility with both CMOS and TTL logic levels. Consider the 2V to 6V operating range for flexibility in supply voltage selection. The TSSOP package is suitable for surface-mount applications where space efficiency is prioritized over through-hole mounting.

Flip Flops Part Context

This part belongs to the HC/UH series of high-speed CMOS logic devices. It is functionally similar to other octal D-type flip-flops but offers specific drive capabilities and speed characteristics defined by the HC family. The device is designed to replace older bipolar logic families while maintaining pin compatibility and improving power efficiency.

Flip Flops Replacement Considerations

Equivalent parts include MM74HC374N and MM74HC374CW from the same manufacturer. Other manufacturers may offer compatible octal D-type flip-flops with three-state outputs, such as those from ON Semiconductor or Texas Instruments, provided they meet the electrical specifications and package requirements.
