Parameter/Condition
Supply Voltage
I/O Supply Voltage
Input Leakage Current: Any input 0V ≤ VIN ≤ VCC (All other pins not under test = 0V)
Input Leakage Address Current (All other pins not under test = 0V)
Output Leakage Current: I/Os are disabled; 0V ≤ VOUT ≤ VCC
Output Levels: Full drive option
High Current (VOUT = VCCQ - 0.373V, minimum VREF, minimum VTT)
Low Current (VOUT = 0.373V, maximum VREF, maximum VTT)
Output Levels: Reduced drive option
