74LV273PW,118

Overview

The 74LV273PW,118 is an octal D-type flip-flop manufactured by Nexperia USA Inc. It features positive-edge triggering and a master reset input. The device operates within a supply voltage range of 1.0 V to 5.5 V. It provides high-speed performance with a propagation delay of 6.5 ns at 3.3 V. The component supports low power consumption and includes overvoltage tolerant inputs up to 5.5 V. It is housed in a 20-TSSOP surface-mount package.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge clock triggering
• Master reset functionality for synchronous data control
• Wide operating voltage range supporting 1.0 V to 5.5 V systems
• Overvoltage tolerant inputs compatible with 5 V devices

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Memory address latching applications
• General-purpose digital storage elements

Procurement Notes

Verify the specific suffix 118 corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status matches current regulatory requirements for your region. Check manufacturer longevity programs for expected order availability periods. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity. Validate pinout compatibility with existing PCB footprints before integration.

Selection Notes

Select this component for designs requiring wide voltage flexibility between 1.0 V and 5.5 V. Consider its overvoltage tolerance for interfacing with 5 V logic levels directly. Evaluate the 6.5 ns propagation delay against system timing constraints. Compare package options if space limitations require alternative form factors beyond TSSOP-20.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices from Nexperia. The LV family offers broader voltage operation compared to standard LVC parts. It serves as a fundamental building block for sequential logic in mixed-voltage environments. The PW suffix indicates the specific TSSOP packaging configuration used for surface mount assembly.

Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same 1.0 V to 5.5 V operating range. Ensure replacement components support the required 6.5 ns speed grade. Confirm package dimensions match the original TSSOP-20 footprint.
