Procurement Notes

Verify the specific suffix 'SJ' against the official datasheet to confirm the SOP-20 package variant. Confirm RoHS compliance status through current manufacturer documentation. Check for obsolescence notices as logic families undergo lifecycle transitions. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Selection Notes

Select this component when requiring high-speed octal latching with tri-state control in a compact surface-mount form factor. Compare propagation delays and output drive strengths against alternative AC or ACT series devices. Verify voltage compatibility with system logic levels. Consider thermal performance requirements within the specified operating temperature range.

Part Context
