It is said that 0V indicates a LOW and 3.3V indicates a HIGH. I was wondering if there is a threshold voltage for the HIGH and LOW logic level. Tried searching it, but couldn't find anything.
Thanks in advance.

The specs you want are VIH and VIL. Download the datasheet from TI for more info.
VIH is 2.0v and VIL is 0.8v. The hysteresis minimum is 0.265v.
