Hello, all
Now we have one inquiry regarding starting up output on TXB0304 from our customer.
Please refer to the item below, and feedback us with your comment.
We found one pulse on B-Port when starting up this device.
The detailed configuration of this device is as below;
A-PortA: 1.8V
B-PortB: 3.3V (This port is starting up 3ms earlier than A-Port)
During this 3ms, we found 1ms pulse on B-Port, if this port is Hi-Z or Pulldown.
As solution of this issue, we tried to have B-Port to Pulldown or OE signal to HIGH after 1.8V was established. However, there still found the pulse.
For your reference, please see the device configuration below;
Please let us clarify how we could resolve this issue.
We thank you in advance for your information.
Best regards,
