SN74AHC273PWRG4

Flip Flops Overview

The SN74AHC273PWRG4 is an octal D-type flip-flop from Texas Instruments' 74AHC logic family, housed in a 20-TSSOP surface-mount package. It features positive-edge triggering and a master reset function. The device operates within a supply voltage range of 2V to 5.5V, supporting a maximum clock frequency of 110MHz. Key electrical parameters include a static current of 4µA, input capacitance of 2.5pF, and a propagation delay of 11ns at 5V with 50pF load. It functions reliably across an industrial temperature range of -40°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops per single integrated circuit
• Positive-edge triggered data capture synchronized with the clock signal input
• Master reset functionality allows simultaneous clearing of all flip-flop outputs
• CMOS technology ensures low static power consumption and high noise immunity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations for data storage and transfer
• General-purpose memory elements in digital control systems
• Timing synchronization and state holding in microprocessor interfaces

Flip Flops Procurement Notes

Verify that the ordering suffix 'G4' confirms compliance with RoHS standards and specifies the specific manufacturing revision. Confirm the package type matches the required 20-TSSOP footprint for PCB layout compatibility. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the manufacturer datasheet for any recent product change notices or pinout updates.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with positive-edge triggering and a global reset is required. The 74AHC series offers speed comparable to 74ALVC while maintaining CMOS power efficiency. Consider the 2V to 5.5V supply range for flexibility in mixed-voltage systems. Verify that the 110MHz maximum frequency satisfies the system clock requirements.

Flip Flops Part Context

This part belongs to the SN74AHC273 series, representing the AHC (Advanced High-Speed CMOS) variant of the standard 74273 octal flip-flop. The 'G4' suffix indicates RoHS-compliant manufacturing. It serves as a direct replacement for older 74HC273 devices where higher speed and lower power are beneficial, while maintaining functional compatibility with standard 74-series logic families.
