Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors due to potential availability constraints. Confirm RoHS compliance status and specific packaging requirements prior to ordering. Review datasheet specifications carefully to ensure compatibility with target voltage levels and timing constraints. Validate that the 20-TSSOP package dimensions align with existing PCB footprint designs.

Selection Notes

Select this component when designing systems requiring octal data storage with high-speed performance at 3.3 V logic levels. Consider the 5.3 ns propagation delay and 150 MHz clock frequency limits for timing analysis. Ensure the 3-state output capability matches the bus architecture requirements. Evaluate thermal management needs given the operating temperature range and surface mount packaging constraints.
