Flip Flops Procurement Notes

Verify the specific suffix 'DGSRQ1' matches the required VSSOP-20 package and reel quantity specifications. Confirm that the Q1 designation aligns with your project's automotive quality requirements. Ensure the voltage range supports your system's 1.65V to 5.5V operational needs. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing orders.

Flip Flops Selection Notes

Select this component when designing automotive systems requiring octal data storage with wide voltage flexibility. It is ideal for interfacing between different voltage domains due to its mixed-mode capability. Consider this part for applications needing high noise immunity and low power dissipation. Ensure the VSSOP-20 package fits your PCB layout constraints and thermal management requirements.

Flip Flops Part Context

This device belongs to the SN74LV273A-Q1 family of octal D-type flip-flops. It is part of Texas Instruments' broader portfolio of automotive-qualified logic ICs. The LV series offers enhanced performance over standard TTL levels while maintaining backward compatibility. This specific variant is optimized for automotive electronics demanding high reliability and strict environmental compliance.

Flip Flops Replacement Considerations

SN74LV273ADGSRQ1 serves as a direct functional substitute within the same automotive grade family. SN74AHCT273QDGSRQ1 offers similar octal D-type functionality but requires a higher 4.5V to 5.5V supply voltage. SN74HCS273QPWRQ1 provides push-pull outputs but operates at a lower maximum frequency. Verify package compatibility and voltage level shifts when substituting.
