TS12A44514 - ‎the equivalent circuit and the connection in case of power off

Hirotaka-san

<Question1>
Do you have ‎the equivalent circuit of TS12A44514?
Could you give us it?

The TS12A44514 is an unbuffered pass FET whose signal path can be ideally modeled as a 0 Ohm wire.  In practice there will be parasitics that are specified in the electrical characteristics table in the datasheet.  There will be slight signal losses and distortions due to the on state resistance (Ron) and the input capacitance (Con).

<Question2>
When the device is the power off or the disabled(INx-off) , the connection between NOX and COMX is disconnect(Hi-z), isn't it?
We can not find it on the datasheet.

You are asking about two different conditions. 

1) When the INx signal is used to select a channel,  the unselected channel or off channel is disconnected or Hi-Z state.  You can see this by the Ioff leakage specification in the datasheet. 

2)   The connection between NOX and COMX is not defined when Vcc = 0V for the TS12A44514.  We do have other switches in our portfolio that have this powered down isolation feature.  This feature will be characterized explicitly stating the Ioff leakage current when Vcc = 0 V.  

Examples:

TS5V330C

TS3DV642
