CD74ACT273EG4

Overview

The CD74ACT273EG4 is an octal D-type flip-flop with separate clocks and a master reset, manufactured by Texas Instruments. It features ACT logic for high-speed operation and low power consumption. The device operates within a voltage range of 2.0V to 6.0V. It includes a common clear input that resets all eight flip-flops to a low state independently of the clock. The package is a 20-pin wide body SOIC (N) with a pitch of 7.5mm.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Master reset function clears all outputs to a low state regardless of clock activity
• ACT logic technology ensures high speed performance while maintaining low power dissipation

Applications

• Data storage registers in digital systems
• Shift register configurations for serial-to-parallel conversion
• Timing control circuits requiring precise clock synchronization

Procurement Notes

Verify the component marking matches the exact part number CD74ACT273EG4. Confirm the manufacturer is Texas Instruments or an authorized licensee. Check for physical damage on pins and the package integrity. Ensure the date code aligns with current supply chain requirements. Request original manufacturer documentation to validate authenticity before integration into production designs.

Selection Notes

Select this component when an octal D-type flip-flop with a global reset is required. It is suitable for applications needing fast switching speeds and low power usage. Consider the 20-pin SOIC package for surface mount assembly constraints. Verify voltage compatibility with the system's operating range between 2.0V and 6.0V. Ensure the clock frequency requirements fall within the specified AC characteristics of the ACT series.

Part Context

This part belongs to the CD74ACT family of high-speed CMOS logic devices. It complements other octal latches and flip-flops in the same series. The EG4 suffix indicates a lead-free, halogen-free variant compliant with environmental standards. It serves as a standard solution for parallel data retention in microprocessor-based systems.

Replacement Considerations

Direct substitutes include the CD74ACT273E from the same manufacturer line. Cross-reference pinouts and electrical specifications carefully when considering alternative vendors. Ensure any replacement maintains the same ACT logic speed and voltage operating ranges.
