Hi TI,
Using FET switch SN74CB3T16211 part 3.3V to 1.8V conversion is possible or not? In Data sheet I/O Support levels mentioned like (0.8V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V) but in DC voltage - Translation characteristics diagram the output will follow the Vcc (Recommended operating Vcc is 2.3V to 3.6V).
The input can be any level since it is a switch. However the lowest is can translate down to is 2.3V.
The bullet is a little misleading.
You could use a dual voltage translater SN74AVC24T245
or a voltage clamp type device SN74TVC16222A (one side must be open drain)
