Urgent Support need.
The customer use TXB0104-q1 in such application.MCU1, slave1 and slave2 are communicating via 4-wire SPI with date rate at 2.5Mbps.They meet two questions about TXB0104.
Q1:Here is how they test: when MCU1 I/O is set high, the slave1 and slave2 get communication with each other via SPI. They find that when IMU_SPI_MISO send data, the SER_SEP_MISO would be pulled down about 0.6V lasting 20ns at 25℃. So they want to know whether this situation would damage the TXB0104 or not. And they find that the Slave1 and Slave2 would get CRC error via SPI communication at -20℃. Could you please have a look on this?
Q2.They also get confused about the timing. Slave1 power up faster than the TXB0104, which means the Slave1 send date to TXB0104 while the TXB0104 would not get power up. Could this will damage the TXB0104？
In such situation, how much voltage of spi will damage the chip?、
