Shift Registers Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to lead-free (RoHS) compliance and NIPDAU finish as documented in the packaging addendum. Confirm the package type matches the required 16-lead PDIP form factor. Ensure the component status is listed as Active for new designs. Cross-reference the manufacturer date code against current production schedules.

Shift Registers Selection Notes

Select this component when an 8-bit parallel load shift register is required for digital logic applications. The CMOS architecture offers advantages in power efficiency compared to older TTL equivalents. Verify that the system voltage requirements fall within the specified 3V to 18V operational window. Consider the through-hole mounting requirement associated with the PDIP package style.

Shift Registers Part Context
