SN74CBTLV3257PWG4

Overview

The SN74CBTLV3257PWG4 is a low-voltage 4-bit 1-of-2 FET multiplexer/demultiplexer from the Texas Instruments CBTLV logic series. It features a 16-TSSOP surface-mount package and operates on a single supply voltage ranging from 2.3 V to 3.6 V. The device supports an operating temperature range of -40°C to +85°C. It contains four independent circuits configured as 4 x 1:2 multiplexers. The component is RoHS compliant and classified under Logic ICs within the Encoders, Decoders, Multiplexers & Demultiplexers category.

Feature Summary

• Provides four independent bidirectional data paths for signal routing
• Supports low-voltage operation compatible with modern digital systems
• Offers flexible configuration as either multiplexer or demultiplexer

Applications

• Portable equipment requiring low power consumption
• Consumer electronics utilizing low-voltage logic interfaces
• Industrial control systems needing signal switching

Procurement Notes

Verify the specific suffix G4 indicates lead-free status and RoHS compliance before procurement. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the 2.3 V to 3.6 V supply range aligns with your system's voltage rails. Check for any recent Product Change Notifications that may affect specifications or manufacturing location. Validate availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing circuits that require multiple low-voltage signal switches in a compact form factor. The CBTLV series is suitable for applications demanding low on-resistance and minimal signal distortion. Consider the TSSOP-16 package if space constraints exist but larger packages are unsuitable. Compare against other CBTLV variants if different pinouts or thermal performances are required for your specific layout.

Part Context

This part belongs to the SN74CBTLV3257 family of low-voltage analog switches. It shares functional similarities with the SN74CBTLV3257PWR and SN74CBTLV3257DR but differs in packaging and environmental compliance markings. The G4 suffix typically denotes lead-free and RoHS-compliant construction. It serves as a direct replacement for older CBT series devices in low-voltage designs.

Replacement Considerations

SN74CBTLV3257PW is a manufacturer-recommended alternative with identical functionality but potentially different packaging or compliance markings.
