CC2642R: What is the VOH AND VOL

pragash sangaran78

Part Number: CC2642R

VOH - Lowest GPIO output voltage reliably interpreted as a High

VOL - Highest GPIO output voltage reliably interpreted as a Low

However, the datasheet of CC2642R only has typical value in the datasheet. Can I have the lowest and highest value, as defined above, for CC2642R?

Hi,

VOH = 0.8*VDDS (Min High)

VOL = 0.2*VDDS ( Max Low)

Thanks,

hi,

are you saying that VIH = VOH and VIL = VOL?

VIH - Lowest GPIO input voltage reliably interpreted as a High

VIL - Highest GPIO input voltage reliably interpreted as a Low

The VOH/ VOL values will be dependent on the current draw. The numbers in the datasheet are given for 4 mA/ 8 mA load. If the load on a DIO is lower the VOL/ VOH values will be closer to the rails.

can i know the limit for the "low" or "Lower"

if i draw maximum currents, 4mA and 8mA, VOH and VOL is as given in the datasheet. if i draw lower current than the maximum, it will follow the rails. how much lower it has to be from the maximum currents?

Hi,

If you have our Launchpad then you can test at your desired load current.

Thanks,
