Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-24 package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering information matches the required temperature grade and pinout specifications for your circuit design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bidirectional bus interface with latching capability is required at 3.3V logic levels. The ABT/LVT technology offers faster switching speeds compared to standard CMOS alternatives. Consider the 24-pin SOIC footprint for PCB layout constraints and thermal dissipation requirements relative to the maximum power dissipation rating.
