SN74CBT3257CD

Overview

The SN74CBT3257CD 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 an operating temperature range from -40°C to +85°C. The device features four independent channels, each capable of connecting one of two inputs to a single output or vice versa. It utilizes a TSSOP-16 surface-mount package for compact integration into electronic circuits.

Feature Summary

• Provides four independent bidirectional switching paths for signal routing
• Enables low-voltage operation compatible with modern digital systems
• Supports both multiplexing and demultiplexing configurations

Applications

• Data acquisition systems requiring signal selection
• Portable battery-powered equipment due to low voltage capability
• Communication interfaces needing signal path management

Procurement Notes

Verify the specific suffix 'CD' against official Texas Instruments documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with your system's voltage levels and thermal requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-voltage, high-speed multiplexer is required for 4-bit data paths. Compare it with other CBTLV series devices if different pin counts or packaging options are needed. Consider the TSSOP-16 footprint constraints during PCB layout design to ensure proper thermal dissipation and signal integrity.

Part Context

This device belongs to the SN74CBTLV3257 family of low-voltage FET multiplexers. It shares functional similarities with other members like SN74CBTLV3257DR but differs in packaging and reel specifications. The CBTLV series is designed for applications demanding low power consumption and fast switching speeds in portable electronics.

Replacement Considerations

SN74CBTLV3257DR is a documented alternative with identical electrical characteristics but in a SOIC-16 package. Verify pinout compatibility and thermal performance differences between TSSOP and SOIC packages before substitution.
