SN74ALS574BNE4

Flip Flops Overview

The SN74ALS574BNE4 is an octal D-type edge-triggered flip-flop with three-state outputs belonging to the Texas Instruments ALS logic series. It features a 20-pin PDIP package and operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a propagation delay of 14 ns, with high-level output current of -2.6 mA and low-level output current of 24 mA. It supports through-hole mounting and 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 allow direct connection to bus lines for efficient data transfer management.
• Advanced Low-power Schottky (ALS) technology ensures reduced power consumption while maintaining high-speed performance.

Flip Flops Applications

• Registering and buffering digital data signals in computer systems.
• Implementing shift registers for serial-to-parallel data conversion.
• Constructing memory arrays and storage elements in logic circuits.

Flip Flops Procurement Notes

Verify the specific ordering suffix 'E4' confirms lead-free compliance and RoHS status as documented by the manufacturer. Confirm the package type corresponds to the required PCB footprint. Ensure the operating temperature range aligns with the system environment requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring moderate speed with low power dissipation. The ALS series offers a balance between performance and energy efficiency compared to standard TTL. Consider the 20-pin DIP package for prototyping or through-hole manufacturing processes where surface mount options are not feasible.

Flip Flops Part Context

This part belongs to the SN74ALS574 family of octal flip-flops. It shares functional compatibility with other variants like SN74ALS574BNSR but differs in packaging. The ALS series represents an evolution from earlier 74S and 74LS families, offering improved speed-to-power ratios for general-purpose digital logic applications.

Flip Flops Replacement Considerations

SN74ALS574BNSR provides identical logical functionality in a surface-mount SOIC-20 package. SN74ACT574N offers faster propagation speeds but requires careful attention to input voltage levels and drive capabilities due to ACT series characteristics.
