LSF0204: Having issue from An to Bn

Yan Pui Chan

Part Number: LSF0204

Hi,

Recently I am working on a design for the I2S interface for the audio speaker, the MCU side is using 1.8V and the amplifier side is using 3.3V. So I picked LSF0204PWR to start with but I am getting an issue for An (1.8V) to Bn (3.3V). Bn only goes up to 1.8V, this translator should be push-pull, right? Do I need pull up resistors on the Bn (3.3V) side in order to make it work?

Thanks

Hello,
This translator is passive -- I would highly recommend watching the video series on it to become familiar with how it works. It should work for your application.
