ACM-012Y and XCM-019Y equip ICs of bus switch with 5V-tolerant level shifter. You can connect them to 5V logics directory.
External inputs exceed 3.3V will be limited and converted into 3.3V level and transfered to FPGA pins.
Here are examples.
Upside:FPGA input (CH.2)
Downside:External Input (CH.1)
- 5V signal input:
