SN74ALS574BN

Flip Flops Overview

The SN74ALS574BN is an octal D-type edge-triggered flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the ALS logic series and features non-inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 14 ns, a high-level output current of -2.6 mA, and a low-level output current of 24 mA. It is housed in a 20-pin PDIP package and supports through-hole installation. The operational temperature range extends from 0°C to +70°C.

Flip Flops Feature Summary

• Contains eight independent D-type edge-triggered flip-flops for parallel data storage.
• Outputs feature three-state capability to facilitate bus-driven systems.
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance.

Flip Flops Applications

• Registering data in digital signal processing circuits
• Buffering memory address or data lines
• Implementing shift register configurations

Flip Flops Procurement Notes

Verify that the ordering suffix matches 'BN' to confirm the specific PDIP-20 through-hole package variant. Confirm RoHS compliance status via official documentation as suffixes may indicate environmental variations. Ensure the application environment remains within the specified 0°C to +70°C operating temperature range for reliable operation.

Flip Flops Selection Notes

Select this component when a TTL-compatible octal latch with three-state outputs is required in a through-hole design. Compare against SN74ALS574BNSR if surface-mount packaging is acceptable. Verify that the 14 ns propagation delay meets system timing requirements and that the 24 mA low-level sink current suffices for the load conditions.

Flip Flops Part Context

This part is a member of the Texas Instruments SN74ALS574B family of octal flip-flops. It shares functional specifications with other variants such as SN74ALS574BNE4, differing primarily in package type and manufacturing revisions. It serves as a standard logic solution for parallel data handling in industrial and commercial applications.

Flip Flops Replacement Considerations

SN74ALS574BNE4 is a direct alternative offering identical electrical characteristics in a PDIP-20 package.
