SN74F374DBR

Flip Flops Overview

The SN74F374DBR is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with positive-edge triggering and three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8.5 ns, a high-level output current of -3 mA, and a low-level output current of 24 mA. It is housed in a 20-pin SSOP package and supports TTL-compatible inputs.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Positive-edge triggered clocking mechanism for precise data capture timing
• Three-state outputs allowing direct bus connection without external drivers
• TTL-compatible input structure ensuring compatibility with standard logic families

Flip Flops Applications

• Parallel data storage registers in digital systems
• Bus-oriented memory applications requiring tri-state isolation
• Clock domain crossing interfaces for synchronous data transfer
• Shift register configurations for serial-to-parallel conversion

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 tape-and-reel packaging format. Confirm that the component meets RoHS compliance requirements for the intended manufacturing process. Ensure the operating temperature range aligns with system thermal constraints. Cross-reference the manufacturer part number against official datasheets to validate pinout and electrical specifications before integration.

Flip Flops Selection Notes

Select this component when an octal flip-flop with fast switching speeds is required. The F-series offers higher performance than LS or HC variants. Consider the SSOP package size for space-constrained PCB layouts. Verify that the three-state output capability matches the bus architecture requirements. Ensure the supply voltage remains within the specified 4.5 V to 5.5 V window for reliable operation.

Flip Flops Part Context

This part belongs to the SN74F series of high-speed CMOS logic devices. It serves as a functional equivalent to other octal D-type flip-flops but with specific speed and drive characteristics defined by the F-family. The DBR suffix indicates surface-mount packaging optimized for automated assembly processes in modern electronics manufacturing.

Flip Flops FAQ

What is the trigger type for the SN74F374DBR?

The device uses positive-edge triggering for all eight flip-flops.

Does the SN74F374DBR have internal reset functionality?

No, the standard SN74F374 does not include an asynchronous clear or preset input; it relies on clock and data inputs for state changes.
