SN74CBTLV3257PWE4

Overview

The SN74CBTLV3257PWE4 is a low-voltage, 4-bit 1-of-2 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports single-supply configurations. The device features four independent SPDT circuits housed in a 16-TSSOP package with dimensions of 0.173 inches (4.40 mm) width. It functions across an ambient temperature range of -40°C to +85°C. The component is RoHS3 compliant and classified under EAR99 with MSL Level 1.

Feature Summary

• Provides four independent single-pole double-throw (SPDT) switching paths for signal routing
• Utilizes FET technology to enable low-voltage operation compatible with modern logic families
• Supports bidirectional data flow for both multiplexing and demultiplexing applications

Applications

• Signal path selection in embedded systems
• Data routing in communication interfaces
• Peripheral management in microcontroller-based designs

Procurement Notes

Verify the specific suffix 'E4' against current manufacturer documentation to confirm compliance status and package details. Confirm availability as distributor records indicate this specific variant may be discontinued or superseded by standard versions. Ensure the selected package matches the required PCB footprint and thermal constraints for the target application environment.

Selection Notes

Select this component when four independent low-voltage analog or digital switches are required within a compact surface-mount form factor. The TSSOP-16 package offers a balance between pin count and board space efficiency. Verify that the operating voltage remains within the 2.3 V to 3.6 V window to ensure proper signal integrity and switching performance.

Part Context

This part belongs to the Texas Instruments 74CBTLV series, designed for low-voltage applications. It serves as a specialized signal switch solution distinct from higher-voltage counterparts. The E4 suffix typically denotes environmental compliance or specific manufacturing lot characteristics defined by the original equipment manufacturer.

Replacement Considerations

The SN74CBTLV3257PW is listed as a manufacturer-recommended alternative. Other potential substitutes include the SN74CBTLV3257PWR and the Renesas 74CBTLV3257PGG8. Verify pin compatibility and electrical specifications before substitution.
