MC74AC574NG

Flip Flops Overview

The MC74AC574NG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features a positive-edge triggered clock mechanism and non-inverting outputs with three-state capability for bus-oriented applications. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 95 MHz. Key electrical parameters include a propagation delay of 9.5ns at 5V with 50pF load, output current drive of 24mA, and static current of 8µA. It is housed in a 20-lead PDIP package and functions identically to the MC74AC374 variant.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors as the part may be obsolete. Confirm RoHS compliance status, as standard versions may not meet current environmental regulations. Check datasheet revisions for pinout consistency with similar models like MC74AC374. Ensure packaging type matches design requirements before ordering.

Flip Flops Selection Notes

Select this component for designs requiring high-speed octal latching with three-state control. Compare against MC74AC374 if opposite-side I/O pinouts are preferred. Verify voltage compatibility across the 2V to 6V range. Consider the 74ACT series if TTL input thresholds are strictly required for interfacing.

Flip Flops Part Context

This component is part of the 74AC family of high-speed CMOS logic devices. It shares functional similarities with the MC74AC374 but differs in physical pinout arrangement. The device is designed for low power consumption while maintaining high-speed performance typical of AC series logic families.

Flip Flops Replacement Considerations

Direct substitutes include MC74AC574DWG. Cross-manufacturer equivalents such as SN74AC574DWR from Texas Instruments or CD74AC574M96 are functionally compatible.
