SN74AHC374DWR

Flip Flops Overview

The SN74AHC374DWR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with three-state outputs, housed in a 20-SOIC package. The device operates within a supply voltage range of 2V to 5.5V and supports a maximum clock frequency of 120 MHz. Key electrical parameters include a propagation delay of 10.1 ns at 5V with 50pF load, output drive currents of ±8 mA, and a static current of 4 µA. It functions across a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Three-state outputs allowing direct connection to bus-oriented systems without external drivers
• Edge-triggered operation synchronized on the positive-going transition of the clock input
• Wide operating voltage compatibility supporting both 3.3V and 5V logic systems

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• Clock buffering and timing synchronization stages
• General-purpose digital data storage applications

Flip Flops Procurement Notes

Verify that the ordering suffix 'R' corresponds to the tape-and-reel packaging format required for automated surface-mount assembly processes. Confirm the specific SOIC-20 footprint dimensions match the target PCB layout constraints. Ensure the component meets RoHS3 compliance standards if environmental regulations apply to the final product assembly. Cross-reference the manufacturer part number against authorized distributor catalogs to guarantee authenticity and traceability.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed octal data latching with low power consumption. The AHC series offers superior speed compared to standard HC logic while maintaining CMOS low-power characteristics. Consider the 120 MHz clock limit and 10.1 ns propagation delay for timing-critical paths. Evaluate the ±8 mA output drive capability against the capacitive load requirements of the connected circuitry to ensure signal integrity.

Flip Flops Part Context

This device belongs to the Texas Instruments 74AHC family of advanced high-speed CMOS logic. It serves as a fundamental building block for sequential logic design, enabling the storage and transfer of multi-bit data words. The SN74AHC374DWR variant specifically utilizes the reel-packaged SOIC-20 form factor, distinguishing it from tube-packaged or alternative pinout versions within the same logical family.
