I'm using 8xTDA1543 from 7V power supply and the current consumption is ~ 600 mA. This means ~ 75 mA per chip. I think it is too high as datasheet shows 50-60 mA so I would expect somethingf like ~ 400 mA. Is it normal?

Well, since they usually work at around 5 volts, the current at 7 volts will be higher. So, it is normal. When they're getting too hot, cool them with a heatsink or something similar...
