Procurement Notes

Verify the specific suffix MTDX to confirm the tape-and-reel packaging configuration required for automated surface-mount assembly processes. Ensure that the procurement source provides valid RoHS compliance documentation and confirms the component's active status, as availability may vary by region. Cross-reference the manufacturer part number with official distributor catalogs to prevent substitution errors during sourcing.

Selection Notes

Select this component when designing circuits that require 16-channel buffering with low voltage operation between 1.2 V and 3.6 V. It is suitable for applications demanding low quiescent current and fast propagation speeds. Consider the TSSOP-48 package constraints regarding board space and thermal management. Compare performance metrics against similar LCX series devices if alternative pinouts or higher drive currents are not required.
