MC74AC574DWR2

Flip Flops Overview

The MC74AC574DWR2 is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features positive-edge triggering and non-inverting three-state outputs within a single 20-SOIC package. The device operates on a supply voltage range of 2V to 6V with a maximum clock frequency of 95 MHz. Key electrical parameters include a propagation delay of 9.5ns at 5V with 50pF load, output current capability of 24mA for both high and low states, and static current of 8µA. Input capacitance is specified at 4.5 pF.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering mechanism
• Non-inverting three-state outputs for direct bus-oriented system interfacing
• CMOS technology providing low static power consumption

Flip Flops Applications

• Parallel data storage in digital systems
• Bus-oriented interface circuits
• High-speed data latching applications

Flip Flops Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Verification of availability should focus on authorized distributors offering surplus stock or approved replacement part numbers such as MC74AC574DWR2G. Ensure compliance with RoHS requirements when selecting substitutes, as the original part does not meet these specifications.

Flip Flops Selection Notes

Designers requiring this specific logic family should consider the MC74AC574DWR2G as a direct functional substitute. Alternatively, cross-reference with Texas Instruments equivalents like SN74AC574DWR for pin-compatible solutions. Verify that the selected replacement maintains the required 2V-6V operating voltage and 24mA output drive capabilities for circuit compatibility.

Flip Flops Part Context

The MC74AC574DWR2 belongs to the standard 74AC574 product line, representing a widely used octal flip-flop configuration. It is housed in a 20-SOIC surface-mount package with a width of 7.50mm. This component serves as a fundamental building block for sequential logic circuits requiring parallel data retention and controlled output tri-stating.

Flip Flops Replacement Considerations

Direct substitute: MC74AC574DWR2G (onsemi). Cross-manufacturer alternatives include SN74AC574DWR (Texas Instruments) and CD74AC574M96 (Texas Instruments). Note that the G suffix indicates RoHS compliance, whereas the base model lacks this certification.
