• Serial-to-parallel conversion interfaces

Shift Registers Procurement Notes

Verify the specific manufacturer marking against official datasheets to confirm authenticity. Ensure the PDIP-16 package matches design requirements. Check RoHS compliance status if required by project specifications. Confirm pinout compatibility with existing PCB layouts before procurement.

Shift Registers Selection Notes

Select this component when a bidirectional shift register with parallel I/O is required. Verify that the HC series voltage and speed characteristics meet system needs. Ensure the through-hole PDIP-16 package is compatible with the manufacturing process. Compare performance against other universal shift registers if higher speeds are needed.

Shift Registers Part Context

This device is part of the broader 74HC logic family, which offers high-speed CMOS operation. It serves as a fundamental building block for digital data movement and storage applications. The N suffix typically denotes a specific package type or lead finish variant within the product line.

Shift Registers Replacement Considerations

Compatible substitutes include the SN74HC194 from Texas Instruments or the MM74HC194 from ON Semiconductor (different prefix). Verify pinout and electrical specifications match exactly before substitution.
