74VHC273MTC

Overview

The Fairchild Semiconductor 74VHC273MTC is an octal D-type flip-flop featuring positive-edge triggering and true outputs. It operates within a supply voltage range of 2V to 5.5V, housed in a 20-lead TSSOP package with a width of 4.4mm. The device supports a maximum operating frequency of 75MHz at nominal supply voltage and delivers a maximum output current of 8mA. It includes a master reset function and exhibits low input capacitance of 4pF, ensuring efficient signal integrity in high-speed digital applications.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge clock triggering
• Master reset functionality for synchronous data initialization
• True non-inverting outputs providing direct data visibility
• Low input capacitance design supporting high-frequency operation

Applications

• High-speed parallel data storage and buffering
• Synchronous state machine implementation
• Data register modules in communication interfaces
• Timing control circuits requiring precise edge-triggered latching

Procurement Notes

Verify the manufacturer designation on the component marking against official Fairchild Semiconductor documentation to confirm authenticity. Ensure the ordering suffix matches the specific tape-and-reel or cut-tape configuration required for your assembly process. Cross-reference the RoHS compliance status and moisture sensitivity level with current environmental declarations prior to procurement to meet regulatory standards.

Selection Notes

Select this component when an octal D-flip-flop with true outputs is required for 2V to 5.5V logic systems. The 75MHz maximum frequency capability makes it suitable for high-speed data paths. Consider the 20-TSSOP package dimensions for PCB layout constraints. Compare propagation delay specifications against system timing requirements to ensure adequate setup and hold times are met during operation.

Part Context

This part belongs to the 74VHC series, representing high-speed CMOS logic technology from Fairchild Semiconductor. The VHC family offers performance comparable to LS TTL but with lower power consumption and wider voltage ranges. As an octal flip-flop, it consolidates eight individual D-type elements into a single package, reducing board space compared to discrete solutions while maintaining standard logic interface compatibility.
