CC2533: V,IH = 2.5V for logic input?

Part Number: CC2533


The logic input 1 on the CC2533 appears to be 2.5V from the data sheet.  This seems quite high for a 3.3V IC.  Is this correct?  We would expect something closer to 2V?

  • Hello Antenna_Head,

    This is the DC characteristic evaluated at VDD = 3 V and is the same parameter value reflected in the datasheet of any CC253X device.  The hysteresis is within ±0.5 V of the target voltage for these devices.
