SN74ALS574BFN

Flip Flops Overview

The SN74ALS574BFN is an octal D-type edge-triggered flip-flop with three-state outputs from the Texas Instruments ALS logic series. It features a PDIP-20 through-hole package and non-inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 14 ns. Electrical characteristics include a high-level output current of -2.6 mA and a low-level output current of 24 mA. It functions within a temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single integrated circuit.
• Three-state outputs enable direct bus connections without requiring additional interface hardware.
• Advanced Low-power Schottky (ALS) technology ensures reduced power consumption while maintaining high-speed performance.

Flip Flops Applications

• Registering data on microprocessor systems
• Buffering memory address lines
• General-purpose digital storage applications

Flip Flops Procurement Notes

Verify component authenticity due to potential availability from third-party distributors. Confirm that the specific BFN suffix corresponds to the PDIP-20 through-hole package variant. Check for end-of-life status or obsolescence notices, as older ALS series components may have limited production runs or require careful sourcing strategies for replacement.

Flip Flops Selection Notes

Select this component when designing circuits requiring octal storage with three-state capability in a through-hole format. Ensure the system operates strictly within the 4.5 V to 5.5 V supply range. Consider the 14 ns propagation delay for timing constraints. Verify thermal requirements against the 0°C to +70°C operating range before implementation.

Flip Flops Part Context

This part belongs to the SN74ALS574B family of octal flip-flops. It shares functional similarities with other variants like the SN74ALS574BDW (SOIC package) and SN74ALS574BNE4 (PDIP package). The primary distinction lies in the physical package type and manufacturing revision indicated by the suffix, while maintaining identical logical and electrical specifications.

Flip Flops Replacement Considerations

SN74ALS574BNE4 offers identical electrical performance in a PDIP-20 package. SN74ALS574BDW provides the same functionality in an SOIC-20 surface-mount package.
