Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC273D,118 are qualified based on the following criteria:

Functional Equivalence: The substitute must be a D-type flip-flop with 8-bit configuration, 1 element, positive edge trigger, and non-inverted output type.

Package Compatibility: The substitute must use the 20-SOIC (0.295", 7.50mm Width) surface mount package to ensure PCB footprint compatibility.

Electrical Parameters: The substitute must operate within overlapping voltage supply ranges and maintain compatible propagation delay characteristics for the intended application frequency.

Compliance & Status: The substitute must be actively produced and maintain equivalent RoHS3 compliance and REACH status.

The SN74LV273ADWR from Texas Instruments meets these substitution criteria as a functionally equivalent 8-bit D-type flip-flop in the same 20-SOIC package with active product status and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 74LVC273D,118 and SN74LV273ADWR are actively produced components with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The primary distinction lies in operating voltage ranges and performance characteristics. The 74LVC273D,118 operates at lower voltage levels (1.65V ~ 3.6V) with higher clock frequency capability (230 MHz) and faster propagation delay (8.2ns @ 3.3V). The SN74LV273ADWR operates across a wider voltage range (2V ~ 5.5V) with lower maximum clock frequency (160 MHz) and slower propagation delay (11ns @ 5V). Selection between these parts depends on the specific voltage supply architecture and timing requirements of the target application. Both parts maintain identical functional architecture, package footprint, and temperature operating range, ensuring direct substitution feasibility within compatible electrical environments.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV273ADWR directly replace the 74LVC273D,118 on an existing PCB?

A: Yes, direct PCB replacement is possible. Both parts use the identical 20-SOIC (0.295", 7.50mm Width) surface mount package with matching pinout and functional architecture. Electrical compatibility must be verified based on the system's supply voltage and timing requirements.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range, clock frequency capability, and propagation delay. The 74LVC273D,118 operates at 1.65V ~ 3.6V with 230 MHz maximum frequency, while the SN74LV273ADWR operates at 2V ~ 5.5V with 160 MHz maximum frequency. Output drive current differs as well, with the 74LVC273D,118 providing 24mA versus 12mA for the SN74LV273ADWR.

Q: Which part should I use for a 3.3V system?

A: Both parts are compatible with 3.3V operation. The 74LVC273D,118 is optimized for this voltage level with faster propagation delay (8.2ns @ 3.3V). The SN74LV273ADWR is also functional at 3.3V but is characterized at 5V with 11ns propagation delay.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and active product status, making them equivalent from a regulatory and supply chain perspective.

Q: What is the significance of the different quiescent current specifications?

A: The 74LVC273D,118 has lower quiescent current (10 µA) compared to the SN74LV273ADWR (20 µA). For battery-powered or low-power applications, the 74LVC273D,118 offers reduced standby power consumption.
