Shift Registers Procurement Notes

Verify the specific suffix PWT against official Texas Instruments documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when designing systems requiring multiple digital inputs with limited microcontroller pins. The HC logic family offers high noise immunity and low power consumption compared to older standards. Confirm that the TSSOP-16 footprint matches your PCB layout constraints and that the voltage levels are compatible with your system's logic thresholds.

Shift Registers Part Context

This device belongs to the widely adopted SN74HC165 family of parallel-load shift registers manufactured by Texas Instruments. It serves as a standard solution for converting parallel data streams into serial formats for digital processing. The HC designation indicates high-speed CMOS technology, ensuring compatibility with various logic families while maintaining robust performance characteristics in demanding electronic environments.

Shift Registers Replacement Considerations

Compatible alternatives include SN74HC165DR and SN74HC165PWR from Texas Instruments, which share identical logical functions but differ in package type or manufacturing revision. Verify pinout compatibility and electrical specifications before substituting.
