Maximum current out of VSS pin ...........................................................................................................................100 mA

Maximum current into VDD pin .............................................................................................................................. 100 mA

Input clamp current, IIK (VI < 0 or VI > VDD) ......................................................................................................... ± 20 mA

Output clamp current, IOK (Vo < 0 or Vo >VDD).................................................................................................... ± 20 mA

Maximum output current sunk by any Output pin.................................................................................................... 25 mA

Maximum output current sourced by any Output pin .............................................................................................. 25 mA

*Notice: Stresses above those listed under “Maximum ratings” may cause permanent damage to the device. This is a

stress rating only and functional operation of the device at those or any other conditions above those indicated in the

operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may

affect device reliability.

Note 1: Power dissipation is calculated as follows: Pdis=VDD x {IDD - Â IOH} + Â {(VDD-VOH) x IOH} + Â(VOl x IOL).
