ABSOLUTE MAXIMUM RATINGS (1)<br />
Symbol Description Max Unit<br />
VTERM Terminal Voltage <strong>with</strong> Respect to GND –0.5 to +6.5 V<br />
TSTG Storage Temperature –65 to +150 °C<br />
IOUT DC Output Current –50 to +50 mA<br />
IIK Continuous Clamp Current, –50 mA<br />
IOK VI < 0 or VO < 0<br />
ICC Continuous Current through each ±100 mA<br />
ISS VCC or GND<br />
NOTE:<br />
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause<br />
permanent damage to the device. This is a stress rating only and functional operation<br />
of the device at these or any other conditions above those indicated in the operational<br />
sections of this specification is not implied. Exposure to absolute maximum rating<br />
conditions for extended periods may affect reliability.<br />
