Hi team,
I have seen that the MIN value of the High-level input voltage is 2V for 3.3V supply. Do we have a same device that has lower VIH than 2V with 3.3V supply (e.g. 1.7V)?

Hi Steve,
The only thing we would have is the 2-channel space-rated device:
SN54SC2T74-SEPRadiation Tolerant, Dual D-Type Flip-Flop With Integrated Translation datasheet

Hi Steve,
Sorry I found a more suitable device that should work, but it's also 2-channel:
SN74LV2T74 data sheet, product information and support | TI.com

Hi Malcolm,
Thanks for your reply.
What is the difference between the 2V and below 2V devices? does they have different technology or focus on different application?
The "T" devices are voltage level translators; they are designed with lower switching thresholds to allow this use case. (This is not the default because this implies a reduced noise margin for 0 V signals.)
