TCA9544A: output default status for TCA9544A

Ben Kuo

Part Number: TCA9544A

Dear team,

For my application, we have multi-slave with same I2C address. And we want to use an I2C mux to access one slave at same time.

Did we have I2C mux solution(4~8 channels) which suitable for this application?

And may I know TCA9544A output default status after power up?

Regards,

Ben

The TCA9544A is suitable for this application.

As shown in table 1, the power-up default state of all downstream channels is disabled.

Hi Ben,

I agree with Clemens' statements. TCA9544A is a suitable 4-channel multiplexing solution for your application.

Upon a successful power-on reset, the registers return to their default state with all channels deselected.

Tyler
