For rise time and fall time specification, see (Δt/ΔV) in the Section 5.3 table.
For specified high and low levels, see (VIH and VIL) in the Section 5.3 table.
Inputs are overvoltage tolerant allowing them to go as high as (VI max) in the Section 5.3 table at any valid VCC.
Recommended maximum Output Conditions:
Load currents should not exceed (IO max) per output and should not exceed (Continuous current through VCC or GND) total current for the part. These limits are located in the Section 5.1 table.
