TXS0108E Power Consumption

jerrry

Hi,

have a question about the max possible source current, which can be expected, when driving VCCA by 1.8V and VCCB by 3.3V and the OE is strappe to VCCA by a 10k. Is this the maximum rating of the "Continious Current Through VCCA, VCCB, GND" with 100mA or what is the expected value?

I need to know the power consumption of this IC. Please could anyone help?

Best Regards.

I have found this thread: h ttps://e2e.ti.com/support/interface/etc_interface/f/391/p/96481/349130#349130

Am I right whe I am using this type of solution and say that 5mA are the supply current. I use all 8 ports of VCCA, so 5mA are enough?

Jerry,

Before I answer, please confirm that you are asking for the maximum amount of current that a power supply must provide to the VCCA and VCCB pins. Is this correct?

Best Regards,

Hi Nirav,

I source the VCCA from another source than the VCCB. There are two separate supplies. So my question is, how much maximum amount of current must the power supply from the VCCA pin support/provide. Thats correct.
