Procurement Notes

Verify the specific suffix 'DLR' corresponds to the 48-SSOP package and tape-and-reel packaging configuration. Confirm RoHS compliance status and manufacturing origin through official Texas Instruments documentation or authorized distributor certificates. Ensure the part number matches the exact revision required for your design, as revisions may impact minor electrical characteristics or pinout definitions. Cross-reference with the latest datasheet to confirm availability and lifecycle status.

Selection Notes

Select this component when an 18-bit wide bus switch is required for high-speed digital signals. It is suitable for designs needing TTL compatibility and low power consumption. Consider the 48-SSOP package constraints regarding PCB space and thermal management. Evaluate the operating voltage range against your system's power supply rails to ensure proper functionality. Compare performance metrics such as on-resistance and propagation delay against alternative bus switches if signal integrity is critical.

Part Context

This device belongs to the Texas Instruments 74CBT series of bus switches and exchangers. The series is known for providing high-speed switching with low power consumption. The SN74CBT16209 variant specifically offers 18-bit width, distinguishing it from narrower 8-bit or 16-bit counterparts.
