Procurement Notes

Verify the component status as End-of-Life (EOL) before procurement planning. Confirm that the manufacturer has officially announced discontinuation and will cease production. Ensure alternative sourcing strategies are established due to potential availability constraints and limited remaining stock from authorized distributors.

Selection Notes

Select this component when designing systems requiring octal latching with three-state control at 3.3 V logic levels. Consider the SOIC-20 package dimensions and thermal characteristics for PCB layout. Evaluate the 5.3 ns propagation delay against system timing requirements to ensure signal integrity in high-speed digital interfaces.
