PCA9306D,112

Translators, Level Shifters Overview

The PCA9306D,112 is a dual bidirectional I2C-bus and SMBus voltage-level translator in an SO8 package. It operates with Vref(1) from 1.0 V to 3.6 V and Vbias(ref)(2) from 1.8 V to 5.5 V. The device supports Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus devices. It provides bidirectional translation between 1.0 V and 5 V without a direction pin. Maximum propagation delay is less than 1.5 ns. ON-state resistance is typically 3.5 Ω. ESD protection exceeds 2000 V HBM and 1000 V CDM.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation for SDA and SCL lines without direction control
• Compatible with Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus protocols
• Low ON-state resistance minimizes signal distortion and propagation delay
• High ESD protection capability for mixed-voltage system integration

Translators, Level Shifters Applications

• Mixed-mode I2C-bus applications connecting different voltage domains
• SMBus interface level shifting
• Connecting low-voltage controllers to high-voltage peripherals

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type and environmental compliance. Confirm that the component version aligns with current manufacturing specifications. Ensure the supplier provides valid traceability documentation. Check for any relevant product change notices affecting the part number or package material before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between 1.0 V and 5 V is required without directional control logic. Ensure the application voltage difference meets the minimum requirement of 1 V between Vbias(ref)(2) and Vref(1). Verify that the open-drain configuration and external pull-up resistors suit the bus capacitance and speed requirements.

Translators, Level Shifters Part Context

This part belongs to the PCA9306 family of dual bidirectional translators. It shares functional characteristics with other variants like PCA9306DC1 and PCA9306DP but differs in physical packaging. The SO8 package offers a standard footprint suitable for general-purpose printed-circuit board routing.

Translators, Level Shifters Replacement Considerations

The Texas Instruments PCA9306DCU and PCA9306DCT share the same footprint and pinout as NXP variants. Verify electrical compatibility and package dimensions before substituting.
