MC74HC273ADTR2

Flip Flops Overview

The MC74HC273ADTR2 is an octal D-type flip-flop manufactured by onsemi, belonging to the MC74HC logic series. It features eight positive-edge-triggered D-type flip-flops with a common clock and active-low asynchronous reset. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a TSSOP-20 package. It is designed for industrial temperature ranges from -55°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Positive-edge triggering mechanism synchronized by a common clock input
• Active-low asynchronous reset function for immediate output clearing
• CMOS output structure ensuring non-inverted data transmission

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Shift register implementations
• Buffering digital signals in control systems

Flip Flops Procurement Notes

Verify the complete part number against official manufacturer documentation, as suffixes such as 'G' or 'Q' indicate specific packaging or quality certifications. Confirm the package type matches the design requirements, as variations exist between TSSOP and SOIC footprints for similar model numbers. Ensure compatibility with the intended operating voltage and temperature range before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when an octal storage solution is required within the HC logic family. Verify that the 2 V to 6 V supply range aligns with the system power rails. Consider the TSSOP-20 package dimensions for PCB layout constraints. Compare propagation delay specifications if high-speed performance is critical, noting that HC series devices may differ significantly from HCT or AC variants in switching characteristics.

Flip Flops Part Context

This component is part of the widely adopted 74HC series of high-speed CMOS logic devices. The 74HC273 specifically provides octal flip-flop functionality, distinguishing it from hex inverters or quad NAND gates within the same family. It serves as a fundamental building block for sequential logic designs requiring parallel data retention.

Flip Flops FAQ

What is the trigger type for the MC74HC273ADTR2?

The device utilizes positive-edge triggering, meaning data is captured at the rising edge of the clock signal.

Does the MC74HC273ADTR2 have a synchronous or asynchronous reset?

It features an active-low asynchronous reset, which clears all outputs independently of the clock signal.
