MC74AC574DTR2G

Flip Flops Overview

The MC74AC574DTR2G is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features eight non-inverting outputs with three-state control, housed in a 20-TSSOP surface-mount package. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 160 MHz. Key electrical parameters include a propagation delay of 10 ns at 5V with 50pF load, output drive currents of ±24 mA, and static current of 4 µA. It functions across an industrial temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type storage elements in a single integrated circuit.
• Three-state output capability allows direct bus driving connections without additional interface hardware.
• High-speed CMOS technology enables operation up to 160 MHz clock frequencies.
• Wide supply voltage compatibility ranging from 2V to 6V for flexible system integration.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementations in microprocessor systems
• Buffering and latching digital signals on system buses
• Timing synchronization and edge detection modules

Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required tape and reel quantity specifications. Confirm that the TSSOP-20 package dimensions align with the target PCB footprint constraints. Ensure the component meets RoHS3 compliance requirements for the intended manufacturing process. Cross-reference the datasheet revision history to confirm pinout consistency with existing designs.

Flip Flops Selection Notes

Select this component when an octal register with high-speed performance and wide voltage tolerance is required. The 74AC series offers faster switching speeds compared to standard 74LS equivalents while maintaining compatible logic levels. Consider the ±24 mA output drive strength for moderate capacitive loads. Evaluate the 10 ns propagation delay against system timing budgets for high-frequency applications.

Flip Flops Part Context

This part belongs to the MC74AC574 family of octal D-type flip-flops. It shares functional similarities with the MC74ACT574DTR2G but differs in supply voltage ranges and speed characteristics. The AC series provides a balance between power consumption and performance suitable for general-purpose digital logic applications requiring multiple storage bits.
