SN74HCS166DYYR

Shift Registers Overview

The SN74HCS166DYYR is an automotive-grade, 8-bit parallel-load shift register from Texas Instruments' HCS logic family. It operates within a wide supply voltage range of 2 V to 6 V and features Schmitt-trigger inputs for noise immunity. The device utilizes a SOT-23-THIN-16 package and supports serial-to-serial data shifting with parallel loading capabilities. It is designed for high reliability in harsh environments, offering low power consumption and robust output drive characteristics suitable for demanding applications.

Shift Registers Feature Summary

• Automotive-grade qualification ensuring reliability in vehicle electronics
• Schmitt-trigger inputs provide enhanced noise immunity for slow or noisy signals
• Wide operating voltage range supports diverse system power requirements

Shift Registers Applications

• Automotive electronic control units
• Industrial data acquisition systems
• Communication interface modules

Shift Registers Procurement Notes

Verify the specific suffix DYYR corresponds to the SOT-23-THIN-16 package and reel packaging configuration. Confirm automotive grade status through official datasheets. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Shift Registers Selection Notes

Select this component when automotive reliability and noise immunity are critical. The HCS series offers improved performance over standard HC logic. Consider the SOT-23-THIN-16 package constraints for space-limited designs. Verify input signal characteristics match the Schmitt-trigger thresholds for optimal operation.

Shift Registers Part Context

Part of the SN74HCSxx series, focusing on high-speed CMOS technology with Schmitt triggers. Designed for automotive and industrial markets requiring robust logic functions in compact packages. Shares functional similarities with other 8-bit shift registers but distinguishes itself through automotive qualification and specific package options.

Shift Registers Replacement Considerations

Check for direct pin-compatible alternatives within the SN74HCS165 or SN74HC165 families if automotive grade is not strictly required. Verify electrical parameters and package dimensions against current design specifications.
