PCA9306: leakage question

Hardy Xue

Part Number: PCA9306

Hi Team,

We have below questions for PCA9306. Could you please help to provide your comments? Thanks.

1. What is the "Disconnect" meaning when EN = Low?

2. When EN= Low, will SCL and SDA pin have leakage to each other?

Best regards

Hardy

The switches are simply N-channel MOSFETs. When EN is low, the gate-to-source voltage is zero or negative, and the transistor is inactive.

The leakage current is specified as I_IH ≤ 5 µA.

Hi Clemens,

Thanks for your reply.

Does I_IH mean device quiescent current or the leakage current of SDA/SCL SW?

Best regards,

Hardy

I_IH is leakage current. There is no quiescent current because this device does not have a power supply.
