Output Clamp Current, IOK (VO <0) .................................................. –50mA

Continuous Output Current, IO ................................................................... ±50mA

Continuous Current through each VCC or GND ............................... ±100mA

Package Thermal Impedance, θJA(3) ............................................................. 40ºC/W

Storage Temperature Range, TSTG ............................................... –65ºC to 150ºC

Note:

Stresses greater than those listed under 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 indi-

cated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions

for extended periods may affect reliability.

Note:

1. The input negative voltage and output voltage ratings may be exceeded

if the input and output current ratings are observed.

2. This value is limited to 4.6V maximum.

3. The package thermal impedance is calculated in accordance with JESD 51.
