SN74HC273QDWRQ1

Flip Flops Overview

The SN74HC273QDWRQ1 is an automotive-grade octal D-type flip-flop with a clear input, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a SOIC-20 package. The device features eight independent D-type flip-flops with positive-edge triggering. Key electrical parameters include a propagation delay of 160 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Flip Flops Feature Summary

Flip Flops Procurement Notes

Verify the specific suffix Q1 indicates automotive qualification status against official Texas Instruments documentation. Confirm the SOIC-20 package dimensions and pinout match your PCB layout requirements. Ensure the operating voltage range aligns with your system's power supply specifications. Check for RoHS compliance details in the latest datasheet revision. Validate that the AEC-Q100 grade meets your project's reliability standards.

Flip Flops Selection Notes

Select this component when automotive certification is mandatory for the application. Choose the HC series for standard speed performance with lower power consumption compared to HCT variants. Consider the SOIC-20 package if space constraints allow for larger footprints than TSSOP options. Verify that the 2 V to 6 V voltage range covers all operational conditions. Evaluate the 160 ns propagation delay against your system timing requirements.

Flip Flops Part Context

This part belongs to the SN74HC273 family of octal D-type flip-flops. The Q1 suffix denotes automotive qualification, distinguishing it from commercial grade parts like the SN74HC273DR. It shares functional compatibility with other HC series devices but offers enhanced reliability for harsh environments. The SOIC-20 package provides a standard footprint for surface-mount assembly processes.
