SN74AS4374BDW

Flip Flops Overview

The SN74AS4374BDW is an octal edge-triggered D-type dual-rank flip-flop manufactured by Texas Instruments. It features 3-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes the AS logic series for high-speed performance and is housed in a 20-SOIC package with a width of 7.50 mm. It supports surface-mount installation and includes non-inverting data paths for both ranks.

Flip Flops Feature Summary

• Dual-rank architecture providing two independent sets of octal storage elements within a single package.
• Edge-triggered operation ensures precise data capture synchronized with clock transitions.
• Three-state output capability allows direct connection to bus systems without external drivers.

Flip Flops Applications

• High-speed parallel data buffering in digital communication interfaces
• Register stages in microprocessor-based memory systems
• State holding circuits in complex logic control units

Flip Flops Procurement Notes

Verify the specific suffix 'BDW' corresponds to the SOIC-20 tube packaging configuration. Confirm that the AS series designation indicates the correct speed grade compared to standard ALS or ABT variants. Ensure compatibility with existing board layouts requiring the 7.50 mm width footprint. Check for any recent product lifecycle notices regarding availability status.

Flip Flops Selection Notes

Select this component when dual independent octal registers are required in a compact form factor. The AS series offers faster propagation delays compared to older TTL families, suitable for high-frequency applications. Verify that the 3-state output drive strength meets the load requirements of the destination circuitry. Consider thermal dissipation capabilities inherent to the SOIC-20 package under continuous operation.

Flip Flops Part Context

This part belongs to the SN74AS4374B family of octal edge-triggered D-type flip-flops. It shares functional similarities with other dual-rank devices but distinguishes itself through the AS logic series characteristics. The BDW suffix specifically denotes the plastic small-outline package variant distributed by Texas Instruments for surface-mount assembly processes.

Flip Flops Replacement Considerations

SN74AS4374BDWE4 is a confirmed equivalent substitute offering identical electrical and mechanical specifications. Verify pinout compatibility before substitution to ensure seamless integration into existing designs without layout modifications.
