Other Parts Discussed in Thread: ISO7741
Hi,
I would like to know the inputs threshold voltage of the ISO7841. In the datasheet is written under the "Recommended Operating Conditions" that:High-level input voltage Min=0.7 × VCCI.
Under "Electrical Characteristics" is written that the Input threshold voltage hysteresis is 0.1xVCCI but is not mentioned the voltage threshold.
Is the Input voltage threshold equal to VCCI*0.5? If yes, the minimum input voltage should be 0.55VCCI (VCCI*0.5+VCCI*0.1*0.5). Where am I wrong?
Thank you
Antonello
