MC74AC574MELG

Flip Flops Overview

The MC74AC574MELG is an octal D-type flip-flop from the 74AC logic series, manufactured by onsemi. It features eight edge-triggered storage elements with a common clock and output enable. The device provides non-inverting, three-state outputs capable of sourcing and sinking 24 mA. It operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a propagation delay of 9.5 ns at 5 V with 50 pF load, a maximum clock frequency of 95 MHz, and static current of 8 µA. It is housed in a 20-SOIC package.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering
• Three-state outputs for bus-oriented applications
• High-speed operation with low power consumption
• TTL-compatible inputs on ACT variants

Flip Flops Applications

• Microprocessor input or output port interfacing
• Bus-oriented data storage systems
• Parallel-to-serial conversion circuits
• General-purpose register applications

Flip Flops Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance status and lead-free packaging details prior to order placement. Check for obsolescence notices or product change notifications (PCN) as this part may be subject to lifecycle changes. Ensure ESD handling procedures are followed during receipt and storage to maintain device integrity.

Flip Flops Selection Notes

Select the MC74AC574MELG when high-speed data latching is required with wide voltage flexibility. The AC series offers faster performance than HC counterparts while maintaining CMOS compatibility. Consider the MELG package variant specifically for SOIC-20 footprint requirements. Evaluate the 24 mA drive capability against load requirements. Compare against MC74ACT574 if TTL input levels are necessary for system interface.

Flip Flops Part Context

This component belongs to the 74AC family of high-speed CMOS logic devices. It is functionally similar to the MC74AC374 but differs in pinout configuration to facilitate easier microprocessor interface design. The device is part of onsemi's broader portfolio of digital logic integrated circuits designed for general-purpose computing and data handling applications.

Flip Flops Replacement Considerations

Public confirmed substitutes include MC74AC574DWR2G. Other compatible alternatives from different manufacturers include CD74AC574M96 and SN74AC574DWR. Verify pinout compatibility and electrical specifications before substitution.
