VIH(max) = VCC + 3.0V for pulse width less than 10ns. 2. VIL(min) = VSS - 3.0V for pulse width less than 10ns. 3. Over/Undershoot specifications are characterized, not 100% tested. 4. Typical values are included for reference only and are not guaranteed or tested. Typical valued are measured at VCC = VCC(TYP.) and TA = 25℃ 5. This parameter is measured at VCC = 3.0V CAPACITANCE (TA = 25 , f ℃ = 1.0MHz) PARAMETER SYMBOL MIN. MAX UNIT Input Capacitance CIN - 6 pF Input/Output Capacitance CI/O - 8 pF Note : These parameters are guaranteed by device characterization, but not production tested.
