The SN74LV273ADW manufactured by Texas Instruments meets all functional and package requirements, operating within compatible electrical parameters while maintaining the same physical footprint and pinout configuration.

Parameter Comparison

Engineering Selection Recommendations

The SN74LV273ADW is a direct functional substitute for the 74LVC273D,112 based on matching core logic architecture, pinout configuration, and package specifications. Both components are ROHS3 compliant and carry MSL Level 1 ratings, ensuring equivalent environmental and regulatory compliance.

The primary design consideration is the supply voltage operating range: the 74LVC273D,112 operates at 1.65V to 3.6V, while the SN74LV273ADW operates at 2V to 5.5V. Systems designed for the lower voltage range of the 74LVC273D,112 must verify that the SN74LV273ADW's minimum 2V supply voltage requirement is compatible with the application. Conversely, the SN74LV273ADW's extended upper voltage limit to 5.5V provides broader compatibility with higher-voltage logic systems.

Secondary electrical differences include propagation delay (8.2ns versus 10.5ns) and output current capability (24mA versus 12mA). These parameters should be evaluated against specific timing and drive requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the SN74LV273ADW directly replace the 74LVC273D,112 in existing designs?

A: Yes, provided the application's supply voltage operates within the SN74LV273ADW's 2V to 5.5V range. The identical 20-SOIC package, pinout, and functional architecture ensure mechanical and electrical compatibility. Designs operating below 2V supply voltage require alternative solutions.

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

A: The primary differences are supply voltage range (74LVC273D,112: 1.65V–3.6V; SN74LV273ADW: 2V–5.5V), clock frequency (230 MHz versus 160 MHz), propagation delay (8.2ns versus 10.5ns), and output current capability (24mA versus 12mA). Both maintain identical functional architecture and package specifications.

Q: Are both parts RoHS compliant?

A: Yes, both the 74LVC273D,112 and SN74LV273ADW are ROHS3 compliant with MSL Level 1 ratings, meeting equivalent environmental and regulatory standards.

Q: Does the package footprint differ between these parts?

A: No, both components use the identical 20-SOIC (0.295", 7.50mm Width) surface mount package with matching pinout and PCB footprint requirements.

Q: Which part should be selected for new designs?

A: Selection depends on supply voltage requirements. For systems operating at 1.65V to 2V, the 74LVC273D,112 is required. For systems operating at 2V and above, the SN74LV273ADW is suitable and offers broader voltage compatibility. Availability and procurement lead times should also be considered, as the 74LVC273D,112 is listed as obsolete.
