PCA9306DCTTE4

Translators, Level Shifters Overview

The PCA9306DCTTE4 is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by Texas Instruments. It operates with VCCA ranging from 1.0 V to 3.6 V and VCCB from 1.8 V to 5.5 V, enabling translation between these domains without direction control pins. The device features an enable input that controls the switch state, providing high-impedance isolation when disabled. Packaged in an 8-pin SM-8 (SSOP) format, it supports standard, fast, and fast-mode plus I2C protocols.

Translators, Level Shifters Feature Summary

• Dual bidirectional channels for simultaneous I2C and SMBus signal translation
• Automatic direction detection eliminates the need for external control pins
• Enable pin functionality allows for bus isolation and power management

Translators, Level Shifters Applications

• Interfacing low-voltage controllers with higher-voltage peripheral devices
• Connecting mixed-voltage I2C buses within embedded systems
• SMBus level shifting in industrial monitoring applications

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, typically SM-8 or SSOP. Ensure the operating voltage requirements of the target system align with the specified VCCA and VCCB ranges before integration.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between 1.0V–3.6V and 1.8V–5.5V domains is required. It is suitable for applications needing automatic direction sensing without GPIO overhead. Consider the enable pin requirement if bus isolation during inactive periods is necessary for the system design.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 series of voltage translators. It is designed specifically for I2C and SMBus interfaces, offering a compact solution for level shifting. The device integrates two independent channels, making it efficient for multi-sensor or multi-device connections on a single bus architecture.

Translators, Level Shifters Replacement Considerations

Check for direct equivalents such as PCA9306DCUR or PCA9306DCTR, ensuring package compatibility. Verify functional equivalence regarding voltage ranges and propagation delay characteristics before substitution.
