SN74CB3Q3306APWR

Overview

The SN74CB3Q3306APWR is a dual FET bus switch from the SN74CB3Q3306A series manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data transfer between 2.5-V and 3.3-V buses. The device features low on-resistance and high bandwidth for signal integrity. It is housed in an 8-pin TSSOP package and is rated for industrial operating temperatures ranging from -55°C to +125°C.

Feature Summary

• Supports dual FET architecture for bidirectional data switching between different voltage domains
• Provides high-bandwidth performance suitable for high-speed digital signals
• Operates with low supply voltage requirements compatible with modern low-power systems

Applications

• Portable equipment requiring low-voltage operation
• Consumer electronics utilizing mixed voltage buses
• Computing and infotainment systems

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-8 package and extended temperature range (-55°C to +125°C) as defined in the official SN74CB3Q3306A datasheet. Confirm RoHS compliance status and manufacturing origin through authorized distributors or the manufacturer's official documentation before procurement.

Selection Notes

Select this component when designing circuits that require switching between 2.5-V and 3.3-V logic levels with minimal signal distortion. Ensure the application demands the extended industrial temperature range provided by the 'PWR' suffix variant rather than the commercial grade options available in the same family.

Part Context

This part belongs to the SN74CB3Q3306A family of dual FET bus switches designed for low-voltage applications. It serves as a bridge for data transmission across different voltage domains, offering high bandwidth and low on-resistance compared to standard logic switches.

Replacement Considerations

SN74CB3Q3306APWRE4 is a verified equivalent part number within the same product family.
