SN74CBT3125DBRE4

Overview

The SN74CBT3125DBRE4 is a quadruple bus switch manufactured by Texas Instruments, designed for high-speed digital signal routing. It operates within a supply voltage range of 2.7 V to 3.6 V and supports bidirectional data transfer across four independent channels. The device features low on-resistance and controlled switching speeds to minimize signal distortion during transmission. Packaged in a 14-pin TSSOP format, it integrates control inputs to manage the state of each channel independently.

Feature Summary

• Provides four independent bidirectional bus switches for flexible signal routing
• Supports low-voltage operation compatible with standard logic families
• Features controlled slew rates to reduce electromagnetic interference

Applications

• High-speed data bus isolation
• Signal multiplexing in communication systems
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS standards when sourcing. Confirm the package type matches the design requirements, as variations exist between tube and reel packaging options. Ensure the operating voltage range aligns with the target system's power supply specifications before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring multiple isolated bidirectional paths within a compact footprint. Consider the propagation delay characteristics relative to the system clock speed. Evaluate the thermal performance under continuous load conditions to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the SN74CBT3125 family of quadruple bus switches from Texas Instruments. It shares functional similarities with other members like the SN74CBT3125PW but differs in package configuration. The series is optimized for consumer electronics and portable equipment where space and power efficiency are critical constraints.

Replacement Considerations

SN74CBT3125PW serves as a pin-compatible alternative with identical electrical characteristics but utilizes a different package style.
