X24257 – Preliminary Information
ABSOLUTE MAXIMUM RATINGS
COMMENT
Temperature under bias ................... –65°C to +135°C Stresses above those listed under “Absolute Maximum
Storage temperature ........................ –65°C to +150°C Ratings” may cause permanent damage to the device.
Voltage on any pin with
respect to V_SS .........................................–1V to +7V
D.C. output current ............................................... 5mA
t Lead temperature
(soldering, 10 seconds).................................. 300°C
This is a stress rating only and the 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 con-
ditions for extended periods may affect device reliability.
