Input hysteresis of ADuM14X and ADuM24X

Question

When I look at the block diagram such as the datasheet figure 1, it seems that the input has a hysteresis characteristic. 
 Does the input voltage have hysteresis characteristics? If yes, what is the voltage

Hi Uboti, 
 There is hysteresis built into the input of the ADuM24xE and it scales based on the supply voltage. Input hysteresis will typically be around 0.4V for a 1.8V supply, 0.6V for 2.5V, 0.8V for 3.3V, and 1.5V for 5V supply. 
 FYI, the new pin-compatible ADuM340E isolators have an input hysteresis specification provided in the datasheet.
