VDD................................................................................................................................................................... 0V to 7.0V
Voltage on RST with respect to Vss.................................................................................................................. 0V to 14V
Total power dissipation (Note 1) .............................................................................................................................. 1.0 W
Maximum source current out of VSS pin ............................................................................................................... 300 mA
Maximum sink current into VDD pin ....................................................................................................................... 250 mA
Input clamp current, Iik (Vi < 0 or Vi > VDD) .......................................................................................................... ±20 mA
Output clamp current, Iok (VO < 0 or VO > VDD).................................................................................................... ±20 mA
Maximum current sunk by any I/O pin..................................................................................................................... 25 mA
Maximum current sourced by any input pin ............................................................................................................ 25 mA
