SN74LVC1G3157: IO Impedance

Allan Fan

Part Number: SN74LVC1G3157

Hi Expert,

Customer would place 1Mohm to ground at Port B and want to know what's the internal Port A impedance to ground? Should it be also high impedance?

Thanks.

Hi Allan,

I don't have the internal impedance at hand, if the customer has the device in their lab, they could measure the resistance from A to GND.

Can you share more details? What is the goal of this MUX and what would the 1Mohm resistor be for?

Thank you and best regards,

Ambroise

Hi Allan,

do you have any news on this issue?

Hi Ambroise,

We are applying samples to verify but it seems we don't have EVM for DCK package.

In addition, do we have Icc curve from 1uA to 10uA?

Thanks.

Hi Allan,

Yes, unfortunately we don't have an EVM for this device. We only have a standard Surface mount adapter.

What kind of Icc curve are you looking for exactly? But chances are low, as we try to put most into the datasheet.

Best regards,

Ambroise
