74ACT273MTCX

Flip Flops Overview

The onsemi 74ACT273MTCX is an octal D-type flip-flop belonging to the 74ACT logic series. It features eight edge-triggered D inputs and corresponding Q outputs, along with a common buffered clock (CP) and master reset (MR). The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It is housed in a SOIC-20 surface-mount package.

Flip Flops Feature Summary

• Contains eight independent edge-triggered D-type flip-flops for parallel data storage
• Includes a common buffered clock input for synchronized operation across all stages
• Features a buffered asynchronous master reset to clear all outputs simultaneously
• Provides strong output drive capability suitable for bus driving applications

Flip Flops Applications

• Buffering signals between MOS microprocessors and memory systems
• Parallel data storage and register functions in digital circuits
• Synchronization of data lines in high-speed communication interfaces
• General-purpose octal latch or register implementations in embedded systems

Flip Flops Procurement Notes

Verify that the specific part number matches the required 74ACT logic family specifications rather than similar HC or AC variants. Confirm the SOIC-20 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer datasheet for any recent pinout or electrical characteristic updates before finalizing the bill of materials.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with TTL-compatible inputs and high drive strength is required. The 74ACT series offers faster switching speeds compared to standard CMOS families while maintaining compatibility with 5V logic levels. Consider the 24 mA output current capability for driving multiple loads or longer traces. Evaluate the 11 ns propagation delay against system timing constraints to ensure signal integrity at the intended operating frequency.

Flip Flops Part Context

This component is part of the widely adopted 74-series logic family, specifically the Advanced CMOS Technology (ACT) subset. It serves as a fundamental building block for sequential logic design, providing reliable data storage and transfer capabilities. The 74ACT273 variant is distinguished by its enhanced speed and drive strength compared to earlier generations, making it suitable for modern digital systems requiring robust performance at 5V operation.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include MC74ACT273DWG from onsemi, which shares identical logical functionality and pin configuration. Other compatible alternatives may exist within the same logic family from different manufacturers, provided they meet the 4.5V to 5.5V supply requirement and SOIC-20 package constraints.
