MAX31915 input logic levels; supply recommendations

Category: Hardware
Product Number: MAX31915

Datasheet does not describe logic levels for DB0 and DB1 logic inputs. Is it CMOS or TTL level? Next, supply level for Vcc24V pin is up to 45V (max 36V recommended), but typical application circuit shows additional required serial 150 Ohm resistor. What is function of this resistor?
