DS16F95QML: Driver output voltage levels & compatibility

Jason Taylor
Prodigy 10 points
Part Number: DS16F95QML

Tool/software:

After reading the datasheet and looking at figures 10&11 it is unclear to me if the common mode / single ended voltage outputs levels are 3V or 5V. My intent is to connect this to an MC/SOC which is 3.3V with a max input voltage of 3.6V. I'm trying to determine if I need a level shifter between the IC output (RO) and the MC/SOC input.

    Hi Jason,

    This is a 5V part and in general there should probably be some type of translator or protection to protect devices connected to "RO" that are operating at 3.6V and less. 

    That being said - this device has a minimum VOH of 2.5V (VCC = 4.5V and IOH = -400uA) - so there is some significant voltage drop between VCC and RO for a logic high under low current - so under most conditions it really should be < 3.6V, but we don't guarantee it will be that low - so a level translator will mitigate that risk. 

    Best,
