Overview

The PCA9306DCUR is a dual-channel, bidirectional voltage level translator that operates without a direction control signal. It enables seamless communication between devices operating on different logic supply rails, supporting a wide range of voltages from 1.2 V to 3.3 V on the low side and 1.8 V to 5.5 V on the high side.

Why Choose This Part

The device features auto-direction sensing, which eliminates the need for a direction control pin and simplifies PCB routing. It supports both open-drain and push-pull output types and maintains a high temperature rating of up to 105 degrees Celsius (TA) for industrial reliability.

Applications

I2C Bus Interfacing
Translating between 1.8 V microcontrollers and 5 V sensors or peripheral devices on an I2C bus.
SMBus Level Shifting
Managing signal levels between system management controllers and battery chargers in portable electronics.
General Purpose Open-Drain Logic
Adapting legacy 5 V logic signals to modern low-voltage CMOS inputs in mixed-voltage embedded systems.

Getting Started

Ensure that VCCB is always greater than or equal to VCCA + 0.6 V for proper operation. When using with I2C, include appropriate pull-up resistors on both sides of the translator to meet the rising edge timing requirements of the bus.
