Voltage level of SDO pin

Category: Datasheet/Specs
Product Number: LTC2484IDD, LTC2484

Hello, 

LTC2484's datasheet electrical characteristics tells VOH of SDO pin can be as low as VCC-0.5V tested at 800uA loading. 

In my application, I am powering LTC2484 with VCC=5.4V & observed that the SDO pin voltage is 4.95V. The SDO pin loads are a pull down resistor of 100k & a buffer IC. The total load amounts to ~55uA. 

As the load is lesser I was expecting a higher VOH for SDO pin. Please can you comment if this expected behavior of the IC.
