SN74LV273ADWR

Flip Flops Overview

The SN74LV273ADWR is an octal D-type flip-flop manufactured by Texas Instruments, featuring positive-edge triggering and a master reset function. It operates within a supply voltage range of 2 V to 5.5 V and supports surface-mount installation in a 20-SOIC package. The component exhibits a maximum propagation delay of 11 ns at 5 V with 50 pF load, ensuring high-speed data handling capabilities. Output drive strength is specified at 12 mA for both high and low states, while static current consumption remains at 20 µA. The device functions reliably across an extended temperature range from -40°C to +125°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit package.
• Positive-edge clock triggering mechanism ensures precise data synchronization on the rising edge of the clock signal.
• Master reset functionality allows immediate clearing of all outputs to a low state regardless of clock or data inputs.
• Wide operating voltage range supports compatibility with various logic families and system power architectures.

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring reliable storage elements.
• High-speed digital buffering and latching applications in communication systems.
• Memory interface modules utilizing wide bus architectures for data capture.
• Industrial control systems operating under extreme temperature conditions.

Flip Flops Procurement Notes

Verify that the ordering suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm the specific variant matches the intended voltage and temperature specifications. Ensure compliance with RoHS3 standards and check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with fast switching speeds and broad voltage tolerance. The 11 ns propagation delay suits high-frequency applications, while the 2 V minimum supply enables low-power operation. Consider the 20-SOIC package dimensions for PCB layout constraints and verify thermal management requirements for operation up to 125°C ambient temperature.

Flip Flops Part Context

This part belongs to the SN74LV series of low-voltage CMOS logic devices, designed for high-speed performance with reduced power consumption. It complements other octal registers like the SN74ALS273DWR and SN74HC273DWR, offering distinct advantages in speed and voltage flexibility. The LVTH273DW provides alternative drive strengths for different load requirements within the same functional family.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74LV273ADWRE4 and SN74LV273ADWRG4. These variants maintain identical electrical characteristics and pin configurations, differing primarily in manufacturing revisions or environmental compliance certifications. Verify package orientation and marking codes when substituting.
