Procurement Notes

Verify the specific suffix 'CDBR' against the manufacturer's current datasheet to confirm package type and commercial grade specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering prefix with official Texas Instruments documentation to validate availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require multiple bidirectional switches within a single integrated circuit. The 20-pin SSOP package offers a compact solution for space-constrained designs. Consider the 4 V to 5.5 V operating range to ensure compatibility with the system's power supply rails and logic voltage levels.

Part Context

This part belongs to the SN74CBT3244 family of octal FET bus switches from Texas Instruments. The family includes various package options such as DGVR and RGYR. These devices are designed to replace traditional mechanical relays or discrete transistor switches in modern digital systems, offering faster switching speeds and smaller form factors.

Replacement Considerations

Direct pin-compatible alternatives include other variants within the SN74CBT3244 series, such as SN74CBT3244DGVR or SN74CBT3244RGYR. Verify electrical parameters and package dimensions before substitution.
