SN74CB3Q3306APWRG4

Overview

The SN74CB3Q3306APWRG4 is a dual FET bus switch from Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 2.5 V to 3.3 V and supports bidirectional data transmission. The device features a TSSOP-8 package and is rated for an operating temperature range from -55°C to +125°C. It belongs to the SN74CB3Q3306A series and is RoHS compliant.

Feature Summary

• Dual FET architecture enabling high-bandwidth signal switching
• Supports 2.5-V and 3.3-V low-voltage logic systems
• Bidirectional data flow capability for flexible bus interfacing

Applications

• Low-voltage digital bus switching
• Portable electronic devices requiring high bandwidth
• Automotive electronics operating in extended temperature ranges

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type is TSSOP-8 and check the operating temperature range covers -55°C to +125°C. Ensure the supply voltage matches the 2.5-V/3.3-V specification before integration into the design.

Selection Notes

Select this component when a dual-channel bus switch is required for 2.5-V or 3.3-V systems. It is suitable for applications demanding high bandwidth and bidirectional data transfer. Consider the wide operating temperature range if the environment exceeds standard commercial limits. Verify pin compatibility with existing PCB layouts using the TSSOP-8 footprint.

Part Context

This part is part of the SN74CB3Q3306A family of dual FET bus switches. It shares functional similarities with other members like the SN74CB3Q3306ADCUR but differs in package and environmental ratings. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing variations within the same functional family.

Replacement Considerations

SN74CB3Q3306ADCUR offers similar functionality in a VSSOP-8 package with a narrower temperature range. SN74CB3Q3306AMPWREP is another variant in the same series. Verify package dimensions and thermal specifications when substituting.
