DS25BR440: which is DS25BR440 output state, when pwdn is 1'b0

Part Number: DS25BR440

Hi, Sir,

Did output of DS25BR440 is Vos, when pwdn is GND? Since I pwdn that tie gnd, output is Vos.

Does it isn't "Hi-Impedance"? If it isn't, could I have chance to let it to become to Hi-Impedance?

Sincerely yours,

Hung Lin

Hi Hung,

When /PWDN is LOW, the output pins will both be biased to the VOS of 1.2V giving you a VOD of 0V. If you want the signal to look like it is high impedance, you could AC-couple it, so that it will appear floating on the other side of the capacitor during this condition.

Regards,

Matt

Hi Matt,

Thank you, If I have to high impedance, I would turn off IC VDD to let it high impedance.
