74LV273DB,118

Overview

The 74LV273DB,118 is an octal D-type flip-flop manufactured by NXP USA Inc. It operates within a supply voltage range of 2.0 V to 3.6 V and features positive-edge triggering with a master reset function. The device provides non-inverting outputs in a 20-pin TSSOP package. Key electrical specifications include a maximum propagation delay of 9 ns at 3.3 V with 50 pF load capacitance, a clock frequency of 150 MHz, and output drive currents of 24 mA for both high and low states. Static current consumption is specified at 10 µA, and the input capacitance is 5 pF.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent storage elements
• Positive-edge clock triggering mechanism synchronized with data inputs
• Master reset functionality to initialize all outputs simultaneously
• Non-inverting output configuration compatible with standard logic levels

Applications

• Parallel-to-serial data conversion circuits
• General-purpose register applications in digital systems
• Data buffering and temporary storage in microcontroller interfaces

Procurement Notes

Verify the manufacturer part number 74LV273DB,118 against official Nexperia or NXP documentation to confirm authenticity. Ensure the component matches the specified 20-pin TSSOP package and operating voltage range. Check for relevant quality certifications such as RoHS compliance and automotive qualification if required for the specific application environment.

Selection Notes

Select this component when an octal D-type flip-flop with a master reset is required for 3.3 V logic systems. Consider the 150 MHz clock speed and 9 ns propagation delay for timing constraints. Verify that the TSSOP-20 package fits the PCB layout requirements and that the 24 mA output drive capability meets the load requirements.

Part Context

This component belongs to the 74LV series of low-voltage CMOS logic devices. It shares functional similarities with other octal flip-flops like the 74LVC273 but differs in supply voltage ranges and switching speeds. The 'DB' suffix indicates the TSSOP-20 package type, while ',118' denotes the specific tape and reel packaging configuration.

Replacement Considerations

Direct substitutes include the 74LVC273D,118 from Nexperia, which offers similar functionality with potentially different electrical characteristics. Other compatible parts may include variants from the 74HC or 74HCT families, though voltage compatibility must be verified.
