Procurement Notes

Verify the specific ordering suffix '118' to confirm the tape and reel packaging configuration required for automated assembly processes. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the manufacturer part number against the latest NXP product change notifications to confirm current production status and availability constraints before finalizing purchase orders.

Selection Notes

Select this component when designing systems requiring eight-bit parallel data retention with tri-state output capability. The wide voltage range makes it suitable for mixed-voltage environments where interfacing between different logic levels is necessary. Consider the 17ns propagation delay and 70MHz clock limit when evaluating timing requirements for high-speed data paths. The TSSOP package selection should align with available PCB footprint constraints and thermal management strategies for surface-mount assembly.
