SN74CBT3125CDGVR

Overview

The SN74CBT3125CDGVR is a quadruple bus switch manufactured by Texas Instruments, designed for high-speed data routing applications. It operates within a supply voltage range of 1.65 V to 3.6 V and features low on-resistance with minimal signal distortion. The device utilizes a TSSOP-14 package suitable for surface-mount assembly. Key electrical characteristics include a maximum propagation delay of 0.8 ns at 3.3 V and an off-state leakage current of less than 1 µA. It supports bidirectional data transmission across four independent channels, ensuring efficient signal integrity in low-voltage digital systems.

Feature Summary

• Provides four independent single-pole single-throw (SPST) switches for flexible bus configuration
• Enables low on-resistance for minimal insertion loss during active signal transmission
• Supports bidirectional data flow between input and output ports without polarity constraints
• Maintains low off-state leakage to prevent signal interference when switches are disabled

Applications

• Portable equipment requiring low-power signal switching
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing high-speed data bus management
• Telecommunications infrastructure components

Procurement Notes

Verify the specific suffix 'DGVR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging quantity and temperature grade. Ensure compatibility with the target PCB footprint dimensions for the TSSOP-14 package. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require multiple independent bus switches operating under low-voltage conditions. Consider the propagation delay specifications if the application demands precise timing synchronization. Evaluate the power consumption requirements relative to the standby leakage currents to ensure system efficiency meets design goals.

Part Context

This part belongs to the SN74CBT3125 family of quadruple bus switches from Texas Instruments. The family is characterized by its ability to handle both AC and DC signals with low distortion. The specific model integrates four switches into a compact form factor, making it suitable for space-constrained designs in modern electronic devices.

Replacement Considerations

Consult the manufacturer's substitution guide for pin-compatible alternatives such as the SN74CBT3125DGR or SN74CBTLV3125 series. Verify that any substitute maintains the same voltage range and package type to ensure seamless integration without redesigning the printed circuit board.
