SN74CB3T3383PWRG4

Overview

The SN74CB3T3383PWRG4 is a 10-bit FET bus-exchange switch designed for low-voltage applications operating at 2.5 V and 3.3 V. It features a 5-V-tolerant level shifter, allowing compatibility with higher voltage logic levels. The device is housed in a 24-TSSOP package and supports an operating temperature range from -40°C to +85°C. This component facilitates efficient data routing within digital systems by providing high-bandwidth switching capabilities while maintaining low power consumption.

Feature Summary

• Integrates a 5-V-tolerant level shifter for seamless interface between low-voltage and 5-V logic domains
• Provides 10-bit FET bus-exchange functionality for flexible signal routing
• Optimized for low-voltage operation at 2.5 V and 3.3 V supply rails

Applications

• Low-voltage bus switching in portable electronic devices
• Signal path translation between 2.5-V/3.3-V and 5-V logic systems
• Data routing in high-density digital communication interfaces

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the datasheet for any recent product change notifications that may affect pinout or electrical characteristics.

Selection Notes

Select this component when a 10-bit bus switch with integrated level shifting is required. It is suitable for designs needing to bridge 2.5-V or 3.3-V logic with 5-V tolerant inputs. Consider the TSSOP-24 package constraints during layout. Evaluate the need for bus-exchange capability versus simple buffering to ensure optimal system performance and cost efficiency.

Part Context

This part belongs to the SN74CB3T3383 family of bus switches from Texas Instruments. It is functionally similar to the SN74CB3T3383PW but includes the 'G4' suffix denoting green/RoHS-compliant manufacturing. It serves as a key component in the broader SN74CB series, which focuses on low-voltage, high-speed switching solutions for modern digital electronics.

Replacement Considerations

The SN74CB3T3383PW is a direct functional equivalent without the RoHS-specific suffix. Verify if the 'E4' or 'RE4' variants are acceptable substitutes based on packaging and compliance requirements. Ensure any replacement maintains the 10-bit configuration and 5-V tolerance specifications.
