MC74AC574N

Flip Flops Overview

The MC74AC574N is an octal D-type flip-flop from the 74AC logic series, manufactured by onsemi. It features eight independent D-type flip-flops with non-inverting outputs and a common Output Enable (OE) input. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a propagation delay of 13.5 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It is housed in a 20-lead PDIP package.

Flip Flops Feature Summary

• Octal D-type flip-flop configuration with single-ended inputs and outputs
• Non-inverting 3-state outputs controlled by a common Output Enable input
• Functionally identical to the MC74AC574DWG variant but in a different package

Flip Flops Applications

• Bus-oriented applications requiring data storage and transfer
• Microprocessor input or output ports
• General-purpose digital logic circuits

Flip Flops Procurement Notes

Verify the specific package type required for your design, as the MC74AC574N uses a PDIP-20 package while other variants like the MC74AC574DWG use SOIC-20. Confirm RoHS compliance status through official manufacturer documentation, as some legacy listings may indicate non-compliance. Ensure the operating temperature range meets your application requirements before finalizing procurement.

Flip Flops Selection Notes

Select the MC74AC574N when an octal D-type flip-flop with 3-state outputs is needed in a through-hole DIP package. Compare it against the MC74AC574DWG if surface mount technology is preferred, noting that both share identical logical functionality. Consider the MC74AC564N if inverted outputs are required instead of non-inverting ones. Verify power supply constraints align with the 2 V to 6 V operating range.

Flip Flops Part Context

This component belongs to the 74AC family of high-speed CMOS logic devices produced by onsemi. It is functionally equivalent to the MC74AC574DWG, differing primarily in packaging. The device is part of a broader line including inverters, buffers, and latches, designed for general-purpose digital applications requiring moderate speed and low power consumption.

Flip Flops Replacement Considerations

The MC74AC574DWG is a direct functional substitute with identical specifications but in an SOIC-20 package. For inverted outputs, the MC74AC564N serves as a compatible alternative. Cross-reference tools should be used to verify pinout compatibility and electrical characteristics before substitution.
