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 over voltage tolerant allowing them to go as high as (VI max) in the Section 5.3 table at any valid VCC.
Recommend Output Conditions
Load currents must not exceed (IO max) per output and must not exceed (continuous current through VCC or GND) total current for the part. These limits are in the Section 5.3 table.
