Part Number: TXS0202 Other Parts Discussed in Thread: LSF0102 There is a usage of TXS0202 for voltage translation between an external USB host ( PC) and an embedded microcontroller that is running at 1.8V,but somthing abnormal happened.

Part Number: TXS0202
I'm using TXS0202YZPR in the project. The A-voltage is 2.5V and B is 3.3V. When set high level on the D-(A) and D+(A), i see that D-(B) is 3.3V, but D+(B) is about 2.0V. I've tested it on two boards. What is the reason? Schematic…
Well for starters, it puts a 3k pullup on the D+ line during "attach" mode, rather than the 1.5K pullup used in the "regular" spec. This results in a lower voltage seen at the CPU than expected for the device detection process, (3//15 instead of 1.5/…
Hi John
IC- USB is just addendum to USB 2.0 spec. It is basically lower power option and meant for chip to chip communication. Max length of the bus cannot exceed 10cm in length. IC-USB is sometimes also referred to as USB-IC or Inter-chip USB.

Mike,
The difference between the TUSB1106 and a basic level shifter like the TXS0202 is the control logic pins the USB ASIC has access to configure the TUSB1106. The TUSB1106 can be configured to transmit and receive serial data at both full-speed…

Hi Abhi,
In terms of the operation, this device is application specific to MMC. But, we understand that there are various requirements as the standards evolve.
I have attached a ppt which could be useful for us and hopefully for you to evaluate the…
