Shift Registers Procurement Notes

Verify the specific suffix S400J against the manufacturer's official datasheet to confirm packaging and marking details. Ensure compatibility with 4.5V to 5.5V supply rails. Check RoHS3 compliance status if required by project specifications. Confirm the 14-TSSOP footprint matches the PCB design. Validate operating temperature range suitability for the intended environment.

Shift Registers Selection Notes

Select this component when a reliable 8-bit serial-to-parallel converter is needed within the 74HCT voltage domain. The TSSOP package offers space efficiency for surface-mount designs. Consider the push-pull output capability for driving loads directly without additional buffering. Verify that the -40°C to 125°C range meets thermal requirements.

Shift Registers Part Context

This part belongs to the widely adopted 74HCT series, known for compatibility with HC logic families while offering TTL-compatible inputs. The 74HCT164 variant specifically provides basic shifting functionality without clocked storage latches on the outputs, making it suitable for direct driving applications where simple data expansion is required.

Shift Registers Replacement Considerations

The MM74HCT164MX from onsemi is listed as a substitute option. Verify pinout compatibility and electrical characteristics before substitution. Ensure the alternative package type matches the existing board layout constraints.
