NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. These are maximum IOL values per output, for 8 outputs turned on simultaneously. Total maximum IOL (all outputs) is 512mA for commercial and 384mA for military. Derate
IOL for number of outputs exceeding 8 turned on simultaneously.
4. The test limit for this parameter is ±5µA at TA = –55°C.
