TC74ACT273P

Flip Flops Overview

The TC74ACT273P is an octal D-type flip-flop manufactured by Toshiba Semiconductor and Storage. It belongs to the ACT logic series, utilizing CMOS technology for high-speed operation. The device features a positive-edge trigger mechanism with non-inverting outputs and includes a master reset function. It operates within a supply voltage range of 4.5V to 5.5V. The component is housed in a 20-pin DIP package designed for through-hole mounting. Key electrical characteristics include a maximum propagation delay of 5.5ns and output drive capabilities of 24mA.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Positive-edge triggering ensures data capture occurs at the rising clock transition
• Master reset functionality allows synchronous clearing of all flip-flop outputs
• High current drive capability supports direct interfacing with standard logic loads

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching digital data buses
• State storage in sequential logic systems
• Register file implementations in microprocessor interfaces

Flip Flops Procurement Notes

Verify the specific manufacturer designation and lot codes upon receipt to ensure authenticity from Toshiba Semiconductor and Storage. Confirm that the DIP-20 package matches the required footprint for PCB layout. Check datasheet revisions for any updates to electrical specifications or recommended operating conditions prior to final design validation.

Flip Flops Selection Notes

Select this component when an octal latch with high-speed ACT performance is required in a through-hole application. Compare against TC74AC273P if lower speed or different voltage ranges are acceptable. Ensure the 5.5V supply constraint aligns with the system power architecture. Consider pin compatibility with other 74ACT series devices for potential design flexibility.

Flip Flops Part Context

This part is part of the broader 74ACT family of high-speed CMOS logic devices. It serves as a functional equivalent to industry-standard 74ACT273 components. The device complements other Toshiba logic ICs such as the TC74ACT573P latch and various D-flip-flop variants like the TC74AC273F, offering consistent interface characteristics across the product line.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include TC74ACT273P(F) and generic equivalents such as SN74ACT273N. Verify pinout compatibility and electrical parameters before substitution.
