TPL0102-100: H to L impedance during power down

Shinya Sawamoto

Part Number: TPL0102-100

Hi team,

I'd like to know if TPL0102 can keep impedance between H to L, not HI-Z state.
As an expectation, remaining 100kohm even in the power down(VDD=0V).
From the description below, it can set by SHDN=High. Is it correct and is there any friendly guidance for that operation?

Thanks in advance.

Hi,

Which impedance you want to be 100K, looking into H terminal? When SHDN is high, switch is closed and the impedance will be 100K looking into H terminal provided Wiper terminal is connected to some high impedance node (Such as Op amp Inverting input). Otherwise it will be function of the code and the impedance from W to ground.

Regards,

Hi AK,

Yes, I meant terminal H to L.
Thanks, I understand that is 100K when W is open and SHDN is high during power down(VDD=0V).
