It's a little confusing on page 20 of the datasheet. The following is copied directly from the datasheet:
1. bottom left on page 20: "The address of the TMP435 is 4Ch (1001100b)."
2. top right on page 20: " The TMP435 supports nine slave device addresses and is available in two different fixed serial interfaces."
3. again on page 20 right column: Table 14 shows 9 strappable addresses using A1 and A0.
So which one is correct out of the above three?
