TS5A23159: Power consumption of TS5A3159 for 5V and 3V input...

The logic input signals at the IN pins should have at least the same voltage as the supply.

What you are seeing are shoot-through currents; see [FAQ] How does a slow or floating input affect a CMOS device?

Hi Peter,

If you are referring the inputs as the logic voltages, then there will be a difference in power consumption for these devices. When the logic inputs are not at the rail voltages (VCC or GND), then there will be additional "shoot through" current that will happen leading to increased power consumption.

Thanks!

Peter,

If you are referring to the digital inputs of the TS5A23159, they will be based off of CMOS. These multiplexers are passive devices and do not drive any outputs, they simply pass the input to the output.

Thanks!
