Hi,
The design has two PCBs, one main board and one daughter card.In the daughter card we are taking VCCA voltage 2.5V from main board and VCCB voltage of 3.3V from daughter card itself.
VCCA- main board
VCCB - daughter card
And the output enable of the voltage level translator is controlled by a GPIO from main board.
We are using the following voltage level translators.Can you please check if the parts are suitable for the above application:
1) SN74AVC8T245RHLR
2) TXB0104PWRG4
3) SN74AVCH8T245RHLR
Is there any other aspects that we should consider for error proof hot swapping of daughter card into main board?
Regards,
Bhavya
