Shift Registers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as sources indicate non-compliance. Check lifecycle status, as some references suggest discontinuation while others list it as active. Ensure the specific orderable part matches the required package and electrical specifications.

Shift Registers Selection Notes

Select this component for designs requiring an 8-bit universal shift register with tri-state outputs. Verify that the 0°C to +70°C operating temperature range meets environmental requirements. Ensure the 4.75V to 5.25V supply voltage aligns with the system power architecture. Consider package availability and lifecycle status before finalizing the design.

Shift Registers Part Context

This component belongs to the 74S series of high-speed Schottky TTL logic devices. It provides universal shift and storage capabilities within an octal configuration. The device is designed for general-purpose digital logic applications requiring data shifting and storage functions with tri-state output control.

Shift Registers Replacement Considerations

Cross-reference documents indicate the DM74S299N may be discontinued. Verify availability of equivalent parts such as the 74LS299 or other 74S series variants. Ensure pin compatibility and electrical specifications match before substitution.
