ABSOLUTE MAXIMUM RATINGS*
Voltage on VCC Supply Relative to VSS........-0.5V to +4.6V
VIN ...........................................................-0.5V to VCC+0.5V
Storage Temperature (plastic) .........................-55oC to +150o
Junction Temperature .....................................................+150o
Power Dissipation ...........................................................1.0W
Short Circuit Output Current .........................................50mA
*Stresses greater than those listed uunder “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.
