MC74AC574M

Flip Flops Overview

The MC74AC574M is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features eight positive-edge-triggered D-type flip-flops with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2V to 6V and supports a clock frequency up to 95 MHz. Key electrical parameters include a maximum propagation delay of 13.5 ns at 5V with 50pF load, output drive currents of ±24 mA, and a static current consumption of 8 µA. It functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs allowing direct connection to bus structures without external buffers
• CMOS technology enabling low power consumption and high noise immunity
• Positive-edge triggering ensures precise data capture synchronized with clock transitions

Flip Flops Applications

• Parallel data storage in digital systems
• Bus driver applications requiring tri-state control
• Register files in microprocessor-based designs
• Shift register configurations for serial-to-parallel conversion

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm RoHS compliance status as historical batches may vary. Check for obsolescence notices or last-time buy notifications from onsemi. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Flip Flops Selection Notes

Select this component when designing circuits requiring octal latching with bus-compatible outputs. Consider the 2V to 6V supply range compatibility with system voltage rails. Evaluate the 13.5 ns propagation delay against timing constraints. Verify that the 20-SOIC package dimensions fit the printed circuit board layout constraints.

Flip Flops Part Context

This part belongs to the 74AC family of high-speed CMOS logic devices. It serves as a standard octal D-type flip-flop solution for general-purpose digital logic applications. The device complements other 74AC series components like the MC74AC573 (octal transparent latch) and MC74AC174 (hex D-type flip-flop).
