MM74HC374WMX

Flip Flops Overview

The MM74HC374WMX is an octal D-type flip-flop manufactured by onsemi, formerly Fairchild Semiconductor. It features eight positive-edge triggered D-type flip-flops with three-state outputs in a 20-SOIC package. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a propagation delay of 40ns at 6V with 150pF load, output currents of 7.8mA for both high and low states, and a static current of 8µA. It functions across a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state outputs enable direct connection to bus lines without additional interface hardware.
• Positive-edge triggering ensures data transfer occurs on the rising transition of the clock signal.
• CMOS technology delivers high noise immunity and low power consumption suitable for battery-powered applications.

Flip Flops Applications

• Bus-organized systems requiring temporary storage and buffering of digital data signals.
• Parallel-to-serial or serial-to-parallel data conversion circuits utilizing shift register configurations.
• General-purpose memory elements in microprocessor-based control systems and embedded logic designs.

Flip Flops Procurement Notes

Verify that the component matches the specific MM74HC374WMX designation rather than generic variants like MM74HC374N or MM74HCT374WM. Confirm the manufacturer source is onsemi, as Fairchild Semiconductor was acquired. Ensure the package type corresponds to the 20-SOIC form factor and check RoHS compliance status against current environmental regulations. Validate that the operating voltage requirements align with your system's power supply specifications before integration.

Flip Flops Selection Notes

Select this component when an octal storage solution with tri-state capability is required for CMOS logic interfaces. Consider the 2V to 6V operating range for compatibility with various logic families. Evaluate the 35 MHz clock speed limit against your system's timing requirements. Compare propagation delays and output drive strengths against alternative logic families such as HCT or VHC if specific voltage translation or faster switching speeds are necessary for the application design.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally equivalent to other octal D-type flip-flops but distinguished by its specific packaging and manufacturing lineage from Fairchild Semiconductor, now under onsemi. The suffix 'WMX' indicates the surface-mount SOIC package and reel tape delivery format. It serves as a standard building block for sequential logic operations in digital electronics.
