SN74CBT3125CPWR

Overview

The SN74CBT3125CPWR is a quadruple bus switch manufactured by Texas Instruments, designed for high-speed digital signal routing. It operates within a supply voltage range of 4 V to 5.5 V and features four independent single-pole single-throw (SPST) switches. The device provides low on-resistance and minimal propagation delay, ensuring efficient data transmission in bus-oriented architectures. Packaged in a 14-TSSOP surface-mount format, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates four independent SPST switches for flexible bus topology management
• Optimized for high-speed data transfer with low propagation delay characteristics
• Supports wide supply voltage operation suitable for standard logic families

Applications

• High-speed data bus switching applications
• Portable equipment requiring low power consumption
• Computing and instrumentation systems

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards relevant to the target manufacturing region. Ensure the ordering part number matches the exact package type and temperature grade specified in the design documentation to avoid compatibility issues during production.

Selection Notes

Select this component when designing circuits that require multiple independent signal paths controlled by a single enable line. It is suitable for replacing older discrete switching solutions to reduce board space. Consider the maximum on-resistance and leakage current specifications against the load requirements of the connected signals to ensure signal integrity is maintained across the operating temperature range.

Part Context

This device belongs to the SN74CBT series of bus switches, which are engineered for low-voltage and high-speed applications. The series offers various configurations to accommodate different pin counts and voltage levels. The SN74CBT3125 specifically addresses needs for quad-channel switching in compact form factors, providing a robust solution for modern electronic designs.

Replacement Considerations

Direct replacements include SN74CBT3125CDR and SN74CBT3125DWR. Verify pinout compatibility and electrical parameters before substitution.
