Teradata extended ASCII is also known as Teradata Latin. It does not mean either ISO-8859-1 or ISO-646-US. The code points from 0x00 to 0x7F match ISO-8859-1 and ISO-646-US. ISO-646-US does not define characters above 7F. Teradata Latin is very similar to ISO-8859-1 but there are maybe 20 characters that are in different.

Teradata latin is indeed a hybrid of ISO 8859-1 and ISO 8859-15. However, various properties of Teradata Latin were fixed predating the ISO 8859-1 standard, which is why Teradata Latin does not conform precisely to any external standard. The ASCII session character set should not be used if characters above ASCII 0x7f are required.

Details of character set support is included in the 'Teradata RDBMS International Character Set Support' manual.
