Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-16 package configuration during sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the component meets the required operating temperature range for your specific application environment. Cross-reference the datasheet revision date to guarantee accurate electrical parameter alignment with your design specifications.

Selection Notes

Select this component when dual-channel 1-of-4 switching is required within a low-voltage operational envelope. The TSSOP-16 package offers a compact footprint suitable for space-constrained printed circuit board layouts. Consider the 40 Ohm on-resistance limit when evaluating signal integrity requirements for high-frequency applications. This part is appropriate for designs transitioning from higher voltage standards to 3.3 V logic families.

Part Context

This device belongs to the SN74CBTLV3253 series of low-voltage analog switches. It serves as a critical interface component for managing signal paths in digital systems. The series is engineered to provide high performance while maintaining low power dissipation. It complements other Texas Instruments logic products by offering reliable multiplexing solutions for complex circuit architectures.

Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family that may offer updated packaging options.
