SN75ALS181 Thermal Shutdown Protection

Other Parts Discussed in Thread: SN75ALS181, SN75LBC180


I have a question about the thermal shutdown protection of SN75ALS181.

The FEATURES of the data sheet of SN75ALS181 has described as "Thermal Shutdown Protection".

Q:Please tell me the detection temperature of the thermal shutdown protection?

SN75LBC180 datasheet 2page "DESCRIPTION (CONTINUED)" :
The devices also provide positive and negative output-current limiting and thermal shutdown for protection from line fault conditions.
The line driver shuts down at a junction temperature of approximately 172°C.

The same temperature Is this description?
