74HC374D

Overview

The Toshiba Semiconductor and Storage 74HC374D is an octal D-type flip-flop featuring positive edge triggering and three-state outputs. It operates within a supply voltage range of 2V to 6V, with a maximum clock frequency of 90 MHz. The device exhibits a maximum propagation delay of 32ns at 6V with 150pF load capacitance. Static current consumption is specified at 4 µA, while output drive capability reaches 7.8mA for both high and low states. It is housed in a 20-SOIC package (0.295 inch width) and supports an operating temperature range from -40°C to 125°C.

Feature Summary

• Octal D-type flip-flop architecture with positive edge-triggered operation
• Three-state non-inverting outputs for bus-oriented applications
• CMOS technology ensuring low static power consumption

Applications

• Bus-oriented memory mapping systems
• Register banks for data storage
• Parallel-to-serial conversion circuits

Procurement Notes

Verify the specific manufacturer designation, as Toshiba Semiconductor and Storage produces this component. Confirm the package variant matches the required 20-SOIC form factor. Ensure the logic family corresponds to standard HC specifications rather than HCT or VHC variants. Check RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when an octal register with tri-state control is required for high-speed digital interfaces. The 90 MHz clock limit suits general-purpose logic applications. Consider the 2V to 6V supply range for compatibility with various logic levels. The wide temperature range supports industrial environments requiring robust thermal performance.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It functions as an octal flip-flop, distinct from latches like the 74HC373. The 20-pin SOIC package provides surface-mount convenience. It serves as a fundamental building block for sequential logic circuits in digital systems.

Replacement Considerations

Cross-reference with Nexperia 74HC374D or ON Semiconductor equivalents for pin-compatible substitution. Verify that alternative manufacturers maintain identical electrical characteristics and package dimensions.
