DIOPI6ULS5V9306SS8-7
Overview
The PI6ULS5V9306SS8-7 is a bidirectional voltage-level translator designed for I2C-bus and SMBus applications. It supports translation between 0.9 V and 3.3 V on the low-voltage side (VCCA) and 1.8 V to 5 V on the high-voltage side (VCCB) without the need for a direction pin. The device features a low ON-state resistance of 3.5 ohms, allowing for minimal signal distortion during high-speed operation.
Why Choose This Part
The component provides a simple flow-through pinout that simplifies PCB routing by placing input and output pins directly opposite each other. It offers high-impedance states when the EN pin is low, ensuring true isolation for sensitive bus segments. Additionally, it is 5V tolerant on I/O ports, making it highly versatile for legacy logic interfacing.
Applications
Key Specifications
Getting Started
When integrating this translator, ensure that VCCB is always at least 0.6V higher than VCCA for proper operation. Connect the Enable (EN) pin to VCCB through a 200k ohm resistor to ensure the device is active during power-up. Refer to the datasheet for calculating appropriate pull-up resistor values based on bus capacitance and desired operating frequency.
