SN74CBT3257CPWG4

Overview

The SN74CBT3257CPWG4 is a 4-bit 1-of-2 multiplexer/demultiplexer from Texas Instruments. It features a single output-enable (OE) input and operates within a supply voltage range of 4 V to 5.5 V. The device supports an operating temperature range from -40°C to +85°C. It is housed in a TSSOP-16 package with surface-mount installation style. This component belongs to the CBT logic series, designed for high-speed signal routing applications.

Feature Summary

• Provides four independent bidirectional data paths for signal switching
• Features low on-resistance for minimal signal distortion
• Includes a single output-enable control input

Applications

• Portable equipment requiring low-voltage operation
• Video and audio signal routing
• High-speed data transmission systems

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the 4V to 5.5V supply voltage range aligns with your system design constraints before finalizing procurement.

Selection Notes

Select this component when a 4-channel multiplexer is required for 5V logic systems. Compare against the SN74CBTLV3257 series if lower voltage operation below 3.6V is necessary. Consider the TSSOP-16 package availability versus other form factors like VQFN based on board space limitations.

Part Context

This part belongs to the SN74CBT3257 family of analog switches. It serves as a replacement for older discrete switching solutions. The device integrates four bilateral switches into a single compact package, reducing board space compared to individual components.

Replacement Considerations

The SN74CBT3257CPW is the non-RoHS equivalent. Verify pin compatibility when substituting with other CBT series devices.
