SN74ABT574ANG4

Flip Flops Overview

The SN74ABT574ANG4 is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the ABT logic series and features a non-inverting polarity with TTL input compatibility. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 6.6 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It is housed in a PDIP-20 package designed for through-hole mounting.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops within a single integrated circuit.
• Three-state outputs enable direct connection to bus structures without external drivers.
• ABT technology ensures high-speed performance with low power consumption characteristics.

Flip Flops Applications

• Buffer registers for data storage and transfer
• I/O port expansion in embedded systems
• Bidirectional bus driver implementations

Flip Flops Procurement Notes

Verify the G4 suffix indicates RoHS compliance and manufacturing changes per Texas Instruments documentation. Confirm the PDIP-20 through-hole package matches your PCB footprint requirements. Ensure the 4.5 V to 5.5 V operating voltage aligns with your system power rails. Check for any specific environmental or handling instructions in the official datasheet before integration.

Flip Flops Selection Notes

Select this component when high-speed octal latching with bus-compatible outputs is required. The ABT series offers superior speed compared to standard HC or HCT logic families. The through-hole PDIP-20 package is suitable for prototyping or applications requiring manual assembly. Verify that the 64 mA low-level sink current meets your load driving needs.

Flip Flops Part Context

This part is a lead-free, RoHS-compliant variant of the SN74ABT574AN. It shares identical logical functionality and pinout with the standard SN74ABT574AN but adheres to stricter environmental standards. It is part of the broader 74ABT574A family, which includes various package options such as SOIC, SSOP, and TSSOP for different mounting requirements.

Flip Flops Replacement Considerations

Direct functional substitutes include SN74ABT574AN and SN74ABT574ANE4. For surface-mount applications, consider SN74ABT574ADWR or SN74ABT574ADBR. Verify package compatibility and ensure the replacement maintains the same ABT logic speed and 3-state output characteristics.
