PCA9306DC1Z

Translators, Level Shifters Overview

The PCA9306DC1Z is a dual bidirectional I2C-bus and SMBus voltage-level translator manufactured by NXP Semiconductors. It operates with Vref(1) ranging from 1.0 V to 3.6 V and Vbias(ref)(2) from 1.8 V to 5.5 V. The device provides bidirectional translation between 1.0 V and 5 V without a direction pin, featuring a maximum propagation delay of 1.5 ns and an ON-state resistance of 3.5 Ω. It utilizes a VSSOP-8 package (SOT765-1), supports Standard-mode, Fast-mode, and Fast-mode Plus I2C protocols, and includes an enable input for high-impedance isolation.

Translators, Level Shifters Feature Summary

• Dual bidirectional translation for SDA and SCL lines in mixed-mode I2C applications
• Low ON-state resistance minimizes signal distortion during data transfer
• Enable input allows switching between active translation and high-impedance isolation
• Symmetrical switch fabrication ensures minimal deviation in propagation delay across channels

Translators, Level Shifters Applications

• Connecting I2C controllers operating at different supply voltages
• Interfacing SMBus devices with varying logic levels
• Mixed-mode I2C bus systems requiring Standard, Fast, or Fast-mode Plus speeds

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix DC1Z corresponds to the VSSOP-8 package variant. Confirm that the required packing method matches the datasheet specifications for this part number. Ensure compatibility with the intended PCB footprint and thermal requirements before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting between 1.0 V and 5 V is required without directional control logic. Ensure the system design accommodates the necessary pull-up resistors on both sides of the translator. Verify that the enable signal timing aligns with the desired isolation and translation states.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 family of voltage translators. It shares functional characteristics with other variants like PCA9306D and PCA9306JK but differs in physical packaging. The DC1Z designation specifically identifies the VSSOP-8 plastic very thin shrink small outline package version.

Translators, Level Shifters Replacement Considerations

The PCA9306DC1/DG is functionally identical and produced in dark green package material. The Texas Instruments PCA9306DCU shares the same footprint and pinout.
