PCA9306DCUT

Translators, Level Shifters Overview

The PCA9306DCUT is a bidirectional voltage level translator from Texas Instruments, designed for I2C and SMBus applications. It features two channels within an 8-pin VSSOP package. The device supports a VCCA range of 1.2V to 3.3V and a VCCB range of 1.8V to 5.5V. It exhibits a maximum propagation delay of 1.4ns at 3.3V. Operating temperatures span from -40°C to +85°C. Output types include open drain and push-pull configurations.

Translators, Level Shifters Feature Summary

• Automatic direction detection for bidirectional data transfer
• Supports both open drain and push-pull output configurations
• Compatible with I2C and SMBus bus standards

Translators, Level Shifters Applications

• I2C bus voltage translation
• SMBus voltage translation
• Connecting low-voltage controllers to higher-voltage peripherals

Translators, Level Shifters Procurement Notes

Verify the specific suffix DCUT corresponds to the tape and reel packaging variant when ordering. Confirm that the 8-pin VSSOP footprint matches the target PCB design. Ensure supply voltage requirements align with the specified VCCA and VCCB ranges before integration into the system architecture.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families operating between 1.2V and 5.5V are required. The dual-channel architecture allows simultaneous translation of multiple lines. Consider the VSSOP package size constraints and thermal performance within the specified industrial temperature range during board layout planning.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 series of bidirectional translators. It serves as a solution for mixed-voltage systems where different logic levels must communicate reliably. The device simplifies interface design by eliminating external components typically needed for level shifting in I2C networks.

Translators, Level Shifters Replacement Considerations

Check for direct pin-compatible alternatives within the same family if supply constraints exist. Verify that any substitute maintains the same voltage ranges and propagation delay specifications to ensure signal integrity in high-speed I2C applications.
