High-level input voltage
V
IH
Indicates the voltage, applied to the input pins of the device, which indicates
the high level state for normal operation of the input buffer.
* If a voltage that is equal to or greater than the “Min.” value is applied, the
input voltage is guaranteed as high level voltage.
Low-level input voltage
V
IL
Indicates the voltage, applied to the input pins of the device, which indicates
the low level state for normal operation of the input buffer.
* If a voltage that is equal to or less than the “Max.” value is applied, the
input voltage is guaranteed as low level voltage.
Hysteresis voltage
