I am using tm4c123g and ds1307 to display time (hh:mm:ss) on sevensegments and date and day on lcd(16x2). Is there any way way to use same 8 pins for data of both (lcd and seven segment display..as they are to diplay different data). Can time multiplexing be used for that purpose? Tell me any idea or any way to do this...

You should be able to share the data lines if you design the hardware correctly as you need something in between. Depending on the number of segments and digits (also the current for each) you can use a seven segment driver like the MAX7219 which is a serially Interfaced (SPI), 8-Digit LED Display Driver.
