Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with official distributor catalogs to avoid substitutions that may alter pinout or electrical characteristics. Confirm moisture sensitivity level handling procedures prior to assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing interfaces between systems operating at different supply voltages, such as 1.8 V and 3.3 V. The LVCH series offers lower dynamic power consumption compared to standard LVC devices. Consider the 48-lead SSOP package for space-constrained PCB layouts. Evaluate the propagation delay specifications against your system's timing requirements to ensure signal integrity across the 16-bit bus width.
