Procurement Notes

Verify the specific suffix 'MEA' corresponds to the 48-pin SSOP package and lead-free status if required by your assembly process. Confirm RoHS compliance documentation matches current regulatory standards. Check for any specific handling instructions related to moisture sensitivity level 1. Ensure the supplier provides original manufacturer datasheets to validate electrical parameters against design requirements.

Selection Notes

Select this component when designing systems requiring 16-bit data latching with tri-state outputs. It is suitable for applications needing compatibility between 3.3V logic cores and 5V I/O interfaces. Consider the 48-SSOP package for space-constrained PCB layouts. Evaluate the propagation delay and drive strength against system timing constraints. Compare with similar LVTH series parts if different pinouts or features are needed.
