SN74ALS574BNSR

Flip Flops Overview

The SN74ALS574BNSR is an octal D-type edge-triggered flip-flop from the Texas Instruments 74ALS logic series. It features eight non-inverting outputs with three-state capability, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input levels. 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 functions reliably across an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture providing eight independent data storage elements.
• Three-state output configuration enabling direct bus line driving and system interconnection.
• Non-inverting polarity ensuring logical consistency between input data and stored output states.

Flip Flops Applications

• Registering data on a system bus for temporary storage.
• Buffering digital signals in high-speed communication interfaces.
• Implementing parallel-to-serial or serial-to-parallel data conversion circuits.

Flip Flops Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape/reel specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the specified industrial temperature range requirements for the target application environment. Cross-reference the datasheet revision to confirm pinout and electrical characteristics remain consistent with design schematics.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with tri-state bus compatibility. The ALS series offers a balance of speed and power consumption suitable for moderate-frequency digital logic. Consider the 20-pin SOIC footprint for surface-mount assembly constraints. Evaluate the 14 ns propagation delay against system timing budgets to ensure signal integrity during clock transitions.

Flip Flops Part Context

This part belongs to the SN74ALS574 family of octal flip-flops. Variants such as SN74ALS574BNSRE4 and SN74ALS574BNSRG4 exist, typically denoting environmental compliance or manufacturing lot codes rather than functional differences. The base model defines the core logic functionality, while suffixes indicate packaging or regulatory attributes verified by the manufacturer.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other 74ALS series devices only if pinouts and electrical specifications match exactly. Do not assume interchangeability with different logic families without detailed parameter comparison.
