SN74CBT3253CPWR

Overview

The SN74CBT3253CPWR is a dual 1-of-4 FET multiplexer/demultiplexer bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4 V to 5.5 V and features –2-V undershoot protection. The device is housed in a TSSOP-16 package and supports surface mount installation. It functions as a high-speed signal routing component with low on-resistance, suitable for applications requiring efficient data path selection.

Feature Summary

• Dual independent 1-of-4 multiplexer/demultiplexer configuration
• Integrated –2-V undershoot protection for input signals
• Low on-resistance for minimal signal attenuation
• Surface-mount TSSOP-16 packaging

Applications

• Portable equipment signal routing
• Consumer electronics data switching
• Computer and telecom equipment bus management

Procurement Notes

Verify the specific suffix 'CPWR' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required pinout and electrical characteristics defined in the latest TI documentation before finalizing procurement.

Selection Notes

Select this component when a dual 1-of-4 switching topology is required within a compact TSSOP-16 footprint. It is appropriate for designs operating between 4 V and 5.5 V that demand low propagation delay and robust input protection against negative voltage transients.

Part Context

This part belongs to the SN74CBT3253C series of 5-V bus switches. It is functionally similar to the SN74CBT3253CDR but utilizes a TSSOP-16 package instead of SOIC-16. The series is designed for high-speed data transmission in portable and consumer applications.

Replacement Considerations

The SN74CBT3253CDR is a direct functional equivalent with identical electrical characteristics, differing only in the SOIC-16 package. Verify pin compatibility during substitution.
