MC74HC273AFG

Flip Flops Overview

The MC74HC273AFG is an octal D-type flip-flop manufactured by onsemi, featuring a common clock and reset mechanism. It utilizes high-performance silicon-gate CMOS technology and operates within a supply voltage range of 2V to 6V. The device provides single-ended outputs with non-inverting polarity and supports through-hole mounting in a 20-SOEIAJ package. Key electrical specifications include a propagation delay of 145 ns, output currents of ±7.8 mA, and a maximum operating temperature of +125°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with common clock and reset functionality
• High-performance silicon-gate CMOS construction for low power consumption
• Non-inverting single-ended output configuration

Flip Flops Applications

• Parallel data storage and buffering
• Shift register applications
• Digital signal processing systems

Flip Flops Procurement Notes

Verify the specific package variant, as MC74HC273AFG denotes the SOEIAJ-20 form factor which differs from standard SOIC or PDIP options. Confirm RoHS compliance status directly with the manufacturer documentation, as historical records indicate variations across different production batches and suffixes. Ensure the selected component matches the required pinout compatibility if replacing legacy LS273 designs.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with a common clock and reset is required in a surface-mountable thin profile. The HC series offers speed comparable to LS logic but with lower power dissipation. Verify that the 2V to 6V operating range aligns with the system's power supply constraints and that the 125°C junction temperature rating suits the thermal environment.

Flip Flops Part Context

This part belongs to the 74HC273A family of octal D-type flip-flops. It serves as a direct pin-compatible replacement for the older 74LS273, offering improved performance characteristics while maintaining identical physical dimensions and pin assignments. The A-series designation indicates enhanced switching speeds and noise immunity compared to earlier iterations.

Flip Flops Replacement Considerations

• MC74HC273AN (PDIP-20)
• MC74HC273ADWG (SOIC-20)
