1 For supply voltages less than ±20 V, the absolute maximum input voltage is

equal to the supply voltage.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

THERMAL RESISTANCE

θJA is specified for worst-case mounting conditions, that is, θJA

is specified for device in socket for CERDIP and PDIP pack-

ages; θJA is specified for device soldered to printed circuit board

for the SOIC package.
