... TH8056 KDC A8 General Description The TH8056 is a physical layer device for a single wire data link capable of operating with various CSMA/CR protocols such as the Bosch Controller Area Network (CAN) version 2.0. This serial data link network is intended for use in applications where a high data rate is not required and a lower data rate can achieve cost reductions in both the physical media components and the microprocessor and/or dedicated logic devices that use the network ...

... The Junction temperature shouldn’t exceed under normal operating conditions the limit specified in chapter 2.3 Static Characteristics. The power dissipation the major factor determining the junction temperature. The TH8056 consumes current in different functions. A part of the supply current goes to the load and the other part dissipates internally ...

... The thermal impedance of an SOIC8 package is about twice in comparison to the thermally enhanced SOIC14 package. Therefore the maximum power dissipation within this package is only about the half. The using of the SOIC8 version of TH8056 depends on the network architecture (number of nodes), the max. ambient temperature and the needed functionality (using of INH pin). ...
