SN74CBT3125PWRG4

Overview

The SN74CBT3125PWRG4 is a quadruple bus switch manufactured by Texas Instruments, designed for high-speed data routing in digital systems. It operates within a supply voltage range of 2.7V to 3.6V and supports bidirectional signal transmission across four independent channels. The device features low on-resistance and minimal propagation delay, ensuring signal integrity during active switching states. It is housed in a 14-pin TSSOP package suitable for surface-mount applications.

Feature Summary

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

Applications

• Portable equipment requiring efficient power management and signal isolation
• Consumer electronics utilizing low-voltage logic interfaces
• Computing peripherals needing high-speed data bus switching

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type matches the design footprint requirements. Ensure the operating voltage range aligns with the target system's power rails. Check for any recent lifecycle notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require multiple isolated bidirectional paths under low-voltage conditions. Consider the TSSOP-14 package constraints regarding thermal dissipation and board space. Evaluate the propagation delay specifications against the maximum clock speeds of the connected devices to ensure timing compatibility within the system architecture.

Part Context

This part belongs to the SN74CBT3125 family of quadruple bus switches. It serves as a variant within Texas Instruments' broader portfolio of level-shifting and switching integrated circuits. The device shares functional similarities with other members of the CBT series but is distinguished by its specific packaging and compliance markings.

Replacement Considerations

Direct substitutes include SN74CBT3125PWR and SN74CBT3125PW. Verify pinout compatibility and electrical characteristics before substitution. Alternative packages such as PW (SOIC) may require mechanical adaptation.
