1.
Caution: this device is not protected in the event of abnormal operating conditions, such as short-circuiting between any
one output pin and ground, between any one output pin and VCC, and between individual output pins.
2.
All voltage values are measured with respect to the ground pin.
3.
When mounted on a 4-layers PCB.
4.
Exceeding the power derating curves during a long period provokes abnormal operating conditions.
5.
Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k
Ω resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
6.
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.

1.
For VCC from 2.4 V to 2.5 V, the operating temperature range is reduced to 0° C≤ Tamb ≤70° C.
2.
For VCC from 2.4 V to 2.5 V, the common mode input range must be set at VCC/2.
3.
Without any signal on VSTBY, the device is in standby.
4.
Minimum current consumption is obtained when VSTBY = GND.
