PCA9570GMH input/output pins Default state ('High' or 'Low')

Hi,

Can anyone help me to find out the default state('High' or 'Low') of

PCA9570GMH on Power on/reset.

In data sheet it is mentioned that on POR (power on reset) device

registers and I2C-bus/SMBus state machine initialize to their default

states. Then what will be the state of input/output pins??

Thanks,

Suresh B

Hi Suresh,

At power-on/reset, all P1 – P4 outputs are HIGH.
