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 V
CC = 5.0V, +25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second.
4. This parameter is guaranteed but not tested.
5. 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 I
OL for number of outputs exceeding 8 turned on simultaneously.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability. No terminal voltage
may exceed V
CC by +0.5V unless otherwise noted.
2. Inputs and V
CC terminals only.
3. Outputs and I/O terminals only.
