SN74CBTLV3257PW

Overview

The SN74CBTLV3257PW is a low-voltage quad 1-of-2 multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data transmission. The device features four independent channels, each capable of functioning as either a multiplexer or demultiplexer. It utilizes FET technology for signal switching and is housed in a 16-TSSOP surface-mount package. The component is designed for applications requiring high-speed data routing with low power consumption.

Feature Summary

• Quad 1-of-2 multiplexer/demultiplexer configuration
• Low-voltage operation from 2.3 V to 3.6 V
• Bidirectional data transmission capability
• FET-based switching technology

Applications

• Portable equipment requiring low power consumption
• High-speed data routing in consumer electronics
• Signal switching in battery-powered devices

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the package type matches the required 16-TSSOP form factor. Check for any recent product change notifications regarding manufacturing site changes or material updates. Ensure compliance with RoHS directives if applicable to your region. Cross-reference the datasheet revision date to confirm the technical specifications align with your design requirements.

Selection Notes

Select this component when a low-voltage, quad multiplexer solution is required for portable or battery-operated systems. The SN74CBTLV3257PW is suitable for designs needing bidirectional data flow and low on-resistance. Consider the TSSOP-16 package constraints for PCB layout. Evaluate the operating temperature range of -40°C to +85°C against environmental conditions. Compare performance metrics such as propagation delay and bandwidth with alternative logic families if higher speed is needed.

Part Context

This part belongs to the SN74CBTLV3257 series of low-voltage FET multiplexers. It is functionally similar to other parts in the CBTLV family but offers specific channel counts and packaging options. The 'PW' suffix indicates the 16-TSSOP package variant. Related parts may include different package styles like RSVR (UQFN) or automotive-grade variants like PWRQ1.

Replacement Considerations

SN74CBTLV3257PWR is a reel-packaged equivalent from Texas Instruments. SN74CBTLV3257PWG4 is a lead-free version previously offered by Texas Instruments. Nexperia offers the 74CBTLV3257PW as a cross-manufacturer alternative.
