Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface-mount package configuration. Confirm that the order quantity aligns with the standard tube packaging format typically associated with this part number variant. Ensure compatibility with the required 1.65 V to 3.6 V supply voltage range for the target application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for low-voltage CMOS applications. The LVC series offers performance comparable to standard 5-V devices while operating at lower voltages. Consider the propagation delay specifications relative to system timing requirements and ensure the SOIC-20 package fits the available PCB footprint constraints.
