Hi Sir,
I used SN74AVC4T774 as below shows:
A connect to FPGA, B connect to output connector;
When initializing FPGA, I tested by multimeter, result is; A port is low level, but B port is high level; after when initialized done, A is low level, B is low level,
HELP: Why B port is high level (when A is low) when initializing FPGA, can you help to check what's wrong with it?
How can I modify the schematic? We need both A and B low level just when during initializing the FPGA.
Please help.
