All inputs within the range: VSS – 0.5 V ≤ VIN ≤ VDD + 0.1 X VDD – where V SS and VDD are appropriate reference pins for a given input pin. (See section on power supply pin descriptions.)
CL = 50 pF unless otherwise noted
Operating ranges define those limits between which the func- tionality of the device is guaranteed.
