Part Number: ISO1410

I'm using ISO1410BDW in a custom design based on "ISO1410DW evaluation module". The Integrated circuit comes to 50 Celsius degree, The R4 is connected and the DNI components are no connected except the TVS in A and B terminals. 

The transmit speed is 100kHz.

The ambient temperature is 29 C and temperature was measured with a thermographic camera.

Vcc1= 5V, Vcc2 =3.3

The current Icc1 and Icc2 are 130mA

Is this a normal functional temperature?

is there any technique to make the IC colder?
