SN74HC374DWR

Flip Flops Overview

The SN74HC374DWR is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 24 MHz. The device features a propagation delay of 230 ns and provides high-level output current of -7.8 mA and low-level output current of 7.8 mA. Packaged in a 20-SOIC format, it functions across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal configuration containing eight independent edge-triggered D-type flip-flops for parallel data storage.
• Three-state outputs allow connection to bus lines without excessive loading or driving requirements.
• CMOS input structure ensures compatibility with standard logic families while maintaining low power consumption.

Flip Flops Applications

• Buffer registers for temporary data storage in digital systems
• I/O ports for interfacing between processors and peripheral devices
• Bidirectional bus drivers for managing data flow on shared communication lines
• Working registers for holding intermediate calculation results

Flip Flops Procurement Notes

Verify the specific package variant matches the required PCB footprint, as the SN74HC374 series includes SOIC, TSSOP, and PDIP options. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Ensure the ordering suffix corresponds to the correct tape-and-reel quantity for automated manufacturing processes.

Flip Flops Selection Notes

Select this component when designing circuits requiring multiple synchronized data latches with high-impedance control capabilities. Consider the 2V to 6V operating range for flexibility in varying supply voltages. Evaluate the 230 ns propagation delay against system timing constraints to ensure signal integrity at the target clock speeds.

Flip Flops Part Context

This device belongs to the Texas Instruments SN74HC374 family of octal D-type flip-flops. It shares functional characteristics with other variants like the SN74HC374N and SN74HC374APWR, differing primarily in packaging technology such as through-hole versus surface-mount configurations while maintaining identical logical operations.

Flip Flops Replacement Considerations

SN74AHC374DWR offers faster switching speeds but requires a 2V to 5.5V supply range. MM74HC374WMX from onsemi provides equivalent functionality in a similar SOIC package. MC74VHC374DWR2G delivers higher performance with lower power consumption but differs in voltage tolerance specifications.
