The
l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. (Note 2), VDD = 48V, VEE = 0V unless otherwise noted.
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to VEE unless otherwise
specied.
