Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package option addendum to confirm the physical package type and reel specifications. Ensure that the selected variant matches the required thermal impedance and moisture sensitivity level for the intended assembly process. Cross-reference the part number with official distribution channels to validate authenticity and production status before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 18-bit wide data paths operating at low voltages between 1.65 V and 3.6 V. The inclusion of active bus-hold functionality simplifies board layout by removing the necessity for discrete pull-up or pull-down resistors. Consider the DL package dimensions if space constraints require a small-outline form factor suitable for surface-mount assembly.
