TC74HC273APF

Flip Flops Overview

The TC74HC273APF is an octal D-type flip-flop manufactured by Toshiba Semiconductor and Storage, belonging to the 74HC logic series. It features a single element with eight bits per element, utilizing positive-edge triggering for data capture. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 78 MHz. Key electrical parameters include a propagation delay of 23ns at 6V with 50pF load, output currents of 5.2mA for both high and low states, and a static current of 8µA. It includes a master reset function and non-inverting outputs. The component is designed for surface or through-hole mounting in a 20-DIP package.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering mechanism
• Integrated master reset functionality for synchronous clearing
• Non-inverting output configuration across all eight channels
• CMOS technology ensuring low static power consumption

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Digital signal processing data latching stages

Flip Flops Procurement Notes

Verify the specific suffix APF corresponds to the 20-DIP package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability for Toshiba Semiconductor and Storage origin. Cross-reference the manufacturer part number against distributor databases to avoid confusion with similar SOP or TSSOP variants. Validate that the component meets the required operating temperature range specifications for the intended application environment.

Flip Flops Selection Notes

Select this component when an octal storage element with through-hole compatibility is required. The 74HC series offers standard CMOS performance suitable for general digital logic applications. Consider the 20-DIP package constraints regarding board space and pin spacing. Evaluate the 2V to 6V supply range against system power rails. Compare propagation delays and drive capabilities against alternative logic families if higher speed or current is needed.

Flip Flops Part Context

This part belongs to the broader 74HC273 family of octal D-type flip-flops produced by Toshiba. It shares functional similarities with other manufacturers' equivalents like the MM74HC273N but differs in packaging and specific electrical characteristics. The APF designation specifically identifies the 20-pin dual in-line package variant within the Toshiba product line, distinguishing it from surface-mount options like the AF or AFN series.
