SN74F374DWR

Flip Flops Overview

The SN74F374DWR is an octal D-type flip-flop from the Texas Instruments 74F series, housed in a 20-pin SOIC package. It features non-inverting outputs with three-state capability and TTL-compatible inputs. 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 supports surface-mount installation and functions within a minimum operating temperature of 0°C.

Flip Flops Feature Summary

• Contains eight independent D-type positive-edge-triggered flip-flops for parallel data storage
• Provides three-state outputs to facilitate direct bus connections without additional interface hardware
• Features TTL-compatible input logic levels for straightforward integration with standard digital systems

Flip Flops Applications

• Parallel data buffering and latching in digital communication interfaces
• Register stages within microprocessor-based system architectures
• Data acquisition systems requiring temporary signal storage before processing

Flip Flops Procurement Notes

Verify the suffix 'DWR' confirms the specific tape-and-reel packaging format and SOIC-20 footprint required for automated assembly processes. Confirm that the manufacturer designation aligns with Texas Instruments specifications to ensure compatibility with existing design files and quality standards. Cross-reference the RoHS compliance status against current environmental regulations applicable to the target deployment region.

Flip Flops Selection Notes

Select this component when high-speed switching characteristics are prioritized over power consumption, as the F series offers faster propagation delays compared to LS or HC variants. Ensure the application environment remains within the specified 0°C minimum operating temperature limit. Verify that the 24 mA low-level sink current capability meets the load requirements of the connected circuitry without exceeding thermal limits.

Flip Flops Part Context

This part belongs to the broader 74F family of high-speed silicon-gate logic devices known for rapid switching performance. It serves as a functional equivalent to other octal flip-flops but distinguishes itself through its specific speed-power profile and three-state output configuration. The device is designed for applications demanding efficient data handling in complex digital logic environments.

Flip Flops FAQ

What is the polarity of the outputs?

The outputs are non-inverting, meaning the Q output follows the D input state upon clock triggering.

How does the three-state feature benefit bus designs?

It allows multiple devices to share a common data line by enabling high-impedance states, preventing signal contention.
