Part Number: DS25BR440

Hi,

During power down mode, how state are each outputs?

My guess is below.

Hi Kuramochi,

This specification is not completely listed in the datasheet.

When the device is active with PWDN# = H the pin OUT+ or OUT- will have ~ 100 Ohm impedance.

When the device is not-active with PWDN# = L the pin OUT+ or OUT- will have ~ 1.5K Ohm impedance.

There will always be a ~ 100 Ohm impedance between OUT+ and OUT- (PWDN# = H or L)

Regards,

Lee

Lee-san,

I understood Power down mode state as below.

I have an additional question.

Does input pin and output separate during power down mode?

In other words, input signal doesn't appear to output pin during power down mode, right?

Best Regards,

Hi Kuramochi-san,

The input and output are not connected when PWDN# = L. No signal will be output from the device.

Lee
