Notes:
(1)
Short-circuits from the output to VCC
+
can cause excessive heating and possible destruction. The maximum
output current is approximately 20 mA and is independent of the VCC
+
magnitude.
(2)
Short-circuits can cause excessive heating and destructive dissipation. Values are typical and for a four-layer
PCB.
(3)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ
resistor between two pins of the device. This is done for all couples of connected pin combinations while the other
pins are floating.
(4)
Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two
pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected
pin combinations while the other pins are floating.
(5)
Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
