SN74CBT3125CD

Overview

The SN74CBT3125CD is a quadruple FET bus switch manufactured by Texas Instruments, designed for high-speed digital signal routing. It operates within a supply voltage range of 2.0 V to 5.5 V and supports bidirectional data transfer across four independent channels. The device features low on-resistance and minimal propagation delay, ensuring signal integrity in complex bus architectures. Packaged in a 14-pin SOIC format, it is suitable for surface-mount applications requiring compact footprints and reliable performance under varying thermal conditions.

Feature Summary

• Provides four independent bidirectional bus switching channels for flexible signal routing
• Supports wide supply voltage operation from 2.0 V to 5.5 V for system compatibility
• Features low on-resistance to minimize signal attenuation during transmission
• Includes controlled rise and fall times to reduce electromagnetic interference

Applications

• High-speed data bus switching in consumer electronics
• Signal routing in portable computing devices
• Interface bridging between different voltage domains
• Memory card slot switching mechanisms

Procurement Notes

Verify the specific suffix 'CD' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure RoHS compliance status matches project requirements. Cross-reference ordering information with authorized distributors to avoid counterfeit components. Confirm lead times and availability directly with the supplier before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple independent bus switches within a single package. Consider the 14-pin SOIC footprint for PCB layout constraints. Evaluate the operating voltage range against the target system's power rails. Assess the propagation delay specifications against the maximum clock frequencies required by the connected peripherals.

Part Context
