We are using TXB0106 IC in our design between PhotoMOS LAA710S and Zynq SOC(XCZ7045-2FFG900I). Snapshot of Schematics is attached for your kind perusal. When GPIO Line from FPGA(Connected to 1.8V bank) is driven low, 2.24V is observed instead of 0V, at other end of buffer TXB0106. Drive strength for GPIO line in FPGA is set to 12mA. Could you please help us to resolve this?
Thanks and Regards
