PCA9306DCUTE4

Translators, Level Shifters Overview

The PCA9306DCUTE4 is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by Texas Instruments. It operates with VCCA ranging from 1.2 V to 3.3 V and VCCB from 1.8 V to 5.5 V. The device features an enable input, supports propagation delays of approximately 1.2 ns to 1.5 ns, and functions within a temperature range of -40°C to +85°C. It is housed in an 8-pin VSSOP package.

Translators, Level Shifters Feature Summary

• Enables bidirectional voltage translation between low-voltage (1.0 V to 3.3 V) and high-voltage (1.8 V to 5.5 V) domains without requiring a dedicated direction control pin.
• Incorporates an active-high enable input that controls the internal switch; when disabled, the device isolates ports via a high-impedance state.
• Supports standard-mode, fast-mode, and fast-mode plus I2C-bus devices as well as SMBus applications.

Translators, Level Shifters Applications

• Interfacing low-voltage microcontrollers with higher-voltage I2C peripherals
• Connecting mixed-voltage systems where different logic levels are present on the same bus
• SMBus communication interfaces requiring level shifting

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental declarations. Ensure the ordering suffix matches the required packaging format. Validate that the part number corresponds to the exact electrical specifications needed for your design.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between 1.2 V–3.3 V and 1.8 V–5.5 V domains is required. Consider the enable pin functionality for bus isolation needs. Evaluate the VSSOP package constraints against PCB layout requirements. Compare propagation delay characteristics against system timing budgets.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 family of dual bidirectional voltage translators. It shares core architecture with variants like PCA9306DCUR and PCA9306DCUT but may differ in packaging or specific manufacturing revisions. The 'E4' suffix typically indicates lead-free and RoHS-compliant construction within the Texas Instruments portfolio.

Translators, Level Shifters Replacement Considerations

Direct substitutes include PCA9306DCUR and PCA9306DCUT. Verify package compatibility and electrical parameter alignment before substitution. Check for any differences in enable pin behavior or operating temperature ranges among these variants.
