Hi there
I buffered the FPGA output pin(with LVC244A). and now I want to drive 8 inputs of another LVC244A with one output of the buffered signal. as the output current of the mentioned buffer is 50mA and the input current is at the 100uA, there should not be any problem.But I do not know why the outputs of last buffer are distorted. for example the rise time of the middle signal is 10ns while the one of the outputs are 50ns. But when I drive just one input of the last buffer everything is ok?
I don know why?
 

Something seems to be wrong with your circuit. Check power supply, enable input, correct connection of all LVC244 pins.
