74LVX273MTC

Overview

The 74LVX273MTC is an octal D-type flip-flop with positive-edge triggering, manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 2.0 V to 3.6 V and features single-ended inputs and outputs. The device is housed in a 20-lead TSSOP package with a width of 4.4 mm. Key electrical parameters include a maximum propagation delay of 20 ns at nominal supply, high-level output current of -4 mA, and low-level output current of 4 mA. It supports a load capacitance of 50 pF and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides eight independent D-type flip-flops for parallel data storage
• Utilizes positive-edge triggering for synchronous data capture
• Features non-inverting true outputs for direct signal interfacing

Applications

• Parallel data register circuits
• Shift register configurations
• Memory buffer applications

Procurement Notes

Verify the manufacturer designation, as this component is also listed under onsemi due to corporate acquisition history. Confirm the specific suffix matches the required package type and lead finish. Ensure compliance with RoHS directives if restricted materials are prohibited in the target assembly process.

Selection Notes

Select this component when designing low-voltage logic systems requiring octal storage capabilities. The LVX series is suitable for interfaces between 1.8 V, 2.5 V, and 3.3 V domains. Consider the 20-ns propagation delay for timing constraints and ensure the 4 mA drive strength meets the load requirements of the downstream circuitry.

Part Context

This part belongs to the 74LVX family, which represents low-voltage CMOS logic optimized for portable and battery-powered applications. The 273 variant specifically denotes an octal D-type flip-flop with clear functionality. It serves as a standard solution for digital state retention in modern embedded systems operating below 3.6 V.

Replacement Considerations

The 74LVX273MTCX is a verified equivalent part number from onsemi, sharing identical logical and physical specifications. Cross-reference pinouts and electrical characteristics before substitution to ensure compatibility with existing board layouts.
