74ABT574AD,118

Flip Flops Overview

The 74ABT574AD,118 is an octal D-type flip-flop with three-state outputs manufactured by NXP USA Inc. It belongs to the ABT logic series and utilizes BiCMOS technology for high-speed operation. The device features a single circuit containing eight bits of data storage. It operates within a supply voltage range of 2.0 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 4.4 ns at 5 V and output drive currents of ±24 mA. The component is housed in a 20-SOIC package and supports surface-mount installation.

Flip Flops Feature Summary

• High-performance BiCMOS construction combining low power dissipation with high speed
• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs allowing direct bus line interfacing without additional drivers

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching operations in digital systems
• High-speed data acquisition systems requiring precise timing control

Flip Flops Procurement Notes

Verify the specific suffix '118' corresponds to the required tape and reel packaging quantity when ordering from distributors. Confirm that the manufacturer designation matches NXP USA Inc. or Nexperia as per recent corporate restructuring records. Ensure RoHS compliance documentation aligns with current environmental regulations for the intended market. Cross-reference the full part number against official distributor catalogs to avoid confusion with similar variants lacking the trailing digits.

Flip Flops Selection Notes

Select this component when system requirements demand high switching speeds alongside moderate power consumption levels typical of BiCMOS technology. The wide operating voltage range facilitates compatibility with both 3.3 V and 5 V logic domains. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate the ±24 mA output drive capability against load requirements to ensure signal integrity across interconnects without exceeding absolute maximum ratings.

Flip Flops Part Context

This device is part of the broader 74ABT family of high-speed logic integrated circuits. It serves as a memory element within complex digital architectures, often replacing older TTL or CMOS counterparts where speed is critical. The ABT series bridges the performance gap between standard AHC and faster ABT devices, offering optimized trade-offs for industrial and consumer applications requiring reliable edge-triggered data storage.

Flip Flops Replacement Considerations

The 74AHC574D,118 serves as a functional substitute within the same package footprint, though it exhibits slower propagation delays due to different underlying technology. Designers must verify voltage level compatibility and drive current limitations when swapping between these variants. Ensure that timing margins in the original design accommodate any differences in switching characteristics between the ABT and alternative logic families.
