TCA9555: Internal IO-Pullup Range?

Franz Schellhase
Expert 3605 points

Part Number: TCA9555

Hi Team,

What range does the internal IO-Pullup of TCA9555DB have, 100kOhm +/- ? Ohm?

The background is that with high impedance input signals at the expander, the levels drift upwards due to the internal pull-up.

Thank you,

Franz
