SN74HCS264QPWRQ1

Shift Registers Overview

The SN74HCS264QPWRQ1 is an automotive-grade, high-speed CMOS hex inverting buffer and driver manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features Schmitt-trigger inputs for enhanced noise immunity. The device provides six independent inverters with outputs capable of driving heavy loads, delivering a low-level output current of 7.8 mA and a high-level output current of -7.8 mA. It exhibits a propagation delay of 5 ns at 6 V with a 50 pF load. Designed for robust performance, it functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a 14-TSSOP surface-mount package and meets AEC-Q100 qualification standards for automotive electronics.

Shift Registers Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package type and tape-and-reel specifications. Confirm that the specific revision matches your design requirements. Cross-reference the datasheet for any recent product change notices or lifecycle status updates before finalizing procurement plans.

Shift Registers Selection Notes

Select this component when designing automotive circuits requiring hex inversion with Schmitt-trigger inputs. Ensure the operating voltage remains between 2 V and 6 V. Verify that the TSSOP-14 package fits the PCB layout constraints. Consider the 5 ns propagation delay for timing analysis in high-speed digital applications.

Shift Registers Part Context

This part belongs to the SN74HCS series, which combines high-speed CMOS technology with Schmitt-trigger inputs. The 'Q' suffix indicates automotive qualification, while 'PWR' denotes the 14-pin TSSOP package. It serves as a specialized variant within the broader SN74 logic family, tailored for demanding automotive environments.

Shift Registers Replacement Considerations

Check for direct pin-compatible alternatives within the SN74HCS family. Verify if non-automotive grades meet the thermal and reliability requirements. Ensure any substitute maintains the same Schmitt-trigger input characteristics and output drive strength.
