Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the SOIC-20 package dimensions align with your printed circuit board footprint specifications. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate authenticity and revision status before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for low-voltage logic applications. The ability to tolerate 5.5V inputs makes it suitable for interfacing between 3.3V devices and legacy 5V systems. Consider the 5.3ns propagation delay for timing-sensitive designs. The SOIC-20 package offers a compact solution for space-constrained layouts while maintaining robust drive capabilities for bus structures.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SNx4LVC540A family of octal buffers and drivers with three-state outputs. It is designed for high-speed digital applications requiring low power consumption and wide operating voltage ranges.
