SN74CB3T3257DGVR

Overview

The SN74CB3T3257DGVR is a multiplexer/demultiplexer integrated circuit manufactured by Texas Instruments. It features four independent 2-to-1 channels configured as a 4 x 2:1 switch array. The device operates on a single power supply ranging from 2.3V to 3.6V and supports surface mount installation in a 16-TVSOP package with a width of 4.40mm. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates four independent bidirectional data paths for signal routing
• Supports low-voltage single-supply operation for energy efficiency
• Provides compact surface-mount packaging suitable for space-constrained designs

Applications

• Portable electronic devices requiring efficient signal path management
• Battery-powered systems utilizing low-voltage logic interfaces
• Industrial control modules operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the 16-TVSOP footprint dimensions. Cross-reference the component status to confirm current production availability before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require multiple independent signal switches within a limited voltage window. The TVSOP package offers a balance between pin count and physical size. Confirm that the system's ground reference and supply rails align with the specified 2.3V to 3.6V operational range for reliable switching performance.

Part Context

This part belongs to the SN74CB3T series, which focuses on high-speed, low-power analog switching applications. The CB3T designation indicates specific electrical characteristics distinct from other variants like the CBTLV or standard CBT series. Understanding these family distinctions is critical for ensuring signal integrity and voltage compatibility in mixed-signal environments.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the SN74CB3T3257DGR or SN74CB3T3257DBVR. Verify pinout compatibility and electrical parameter alignment before implementing any alternative components in the design.
