Hello,
I have interfaced TXB 102 DCT Package between a 5 V microcontroller and a wifi module.Microcontroller outputs TX and RX uart signals and is fed by 5V.
WiFi module is fed by 3.3V and and TX,RX pins from the micro are interfaced to this module through TXB.
My connection is as follows.
TXB Pin Number 1-----> TX from Micro(Between 5V to 0V)
TXB Pin Number 2-----> GND
TXB Pin Number 3------> 3.3V
TXB Pin Number 4-------> Level Converted TX of micro to the RX of the wifi module(Shall be between 3.3V and 0V)
TXB Pin Number 5------>Level Converted RX of micro to the TX pin of the wifi module(Shall be between 3.3V and 0V)
TXB Pin Number 6------>Connected to 3.3V
TXB Pin Number 7------->5V
TXB Pin Number 8----->RX from Micro(Between 5V and 0V)
When i send a UART TX signal to the Pin number 1 i expect to read that signal from pin 4.However there is no output on any pins.
Could you please verify if the connections are true.
Thanks,
