DS25CP114: Output power down

Marijn Tiggelman

Part Number: DS25CP114

According to the Control Register table on page 16 of the datasheet, the individual outputs can be powered down. It is not mentioned anywhere however what this means:

Do the outputs go to High-Z?
Do they go to a fixed value?

Greetings,

All circuitry is shut down and thus output is in high impedance(high-Z).

Thanks a lot.

Just as a sanity check: the 100 Ohm termination will still be active/present when the output is shut down?

Hi Marjin,

When output is shutdown, output is high impedance in order Kilo ohms not 100 ohm.

Hi Nasser, Marijn wanted to ask in case of output off, which of the following case will be true?

Hi Aviral,

Top diagram - no 100-ohm on the ouput.
