74ABT574CSJ

Flip Flops Overview

The Fairchild Semiconductor 74ABT574CSJ is an octal D-type flip-flop belonging to the ABT logic series. It features eight edge-triggered D-type inputs and single-ended outputs housed in a SOP-20 package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a propagation delay of 5 ns. Output drive capabilities include -32 mA high-level current and 64 mA low-level current. It functions as a non-inverting buffer suitable for bus-oriented applications.

Flip Flops Feature Summary

• Edge-triggered D-type inputs with buffered positive edge-triggered clock
• Single-ended outputs designed for bus-oriented applications
• High output sink capability of 64 mA and source capability of 32 mA
• Glitch-free bus loading during power up and power down cycles

Flip Flops Applications

• Bus-oriented data storage systems
• Microprocessor interface circuits
• Input or output port buffering
• Parallel data latching applications

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity and pin alignment against SOP-20 specifications. Ensure operating conditions remain within the specified 4.5 V to 5.5 V voltage range and -40°C to +85°C temperature limits. Check RoHS compliance status prior to integration.

Flip Flops Selection Notes

Select this component when high-speed octal latching with strong drive currents is required. The ABT series offers superior performance compared to standard AC/ACT families. Verify that the single-ended output configuration meets system requirements rather than three-state alternatives. Ensure the SOP-20 footprint fits the target PCB layout constraints.

Flip Flops Part Context

This part belongs to the Fairchild ABT logic family, which combines advanced CMOS technology with TTL-compatible inputs. The 74ABT574 variant specifically provides octal configuration without three-state outputs, distinguishing it from the 74ABT374. It serves as a high-performance solution for parallel data handling in digital systems.

Flip Flops Replacement Considerations

The 74ABT374CSC is a functional substitute featuring identical logic but includes three-state outputs. Verify if the additional OE pin compatibility aligns with the existing circuit design before substitution.
