Hi expert,
Customer used TXB0108 for SDIO and found out the communication would fail if there is no enough delay time on OE. It works if adding over 1s delay.
Could you please clarify if it is expected and what's the minimum delay requirement?
Here is an example that OE is enable 0.6s after Vccb 3,3V ready.
Yellow: Vcca 1.8V
Blue: Vccb 3.3V
Purple: OE
Regards,
Allan
