SN74AVC4T245: Sn74avc4t245 heating problem

Dear sir/madam,

I am using sn74avc4t245 buffer in my design. I am driving Enable pins and Direction control pins from the FPGA. Enable pins and Direction control pins are pulled up to VCCA through 4.7k resistors. I have grounded the unused pins. But the buffer is drawing more current and getting heated up very badly.

Thanks in advance...
