CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. θ_JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
2. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θ_JC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
Electrical Specifications
Unless Otherwise Specified, T_A = -40^oC to 85^oC for industrial (I) grade and T_A = 0^oC to 85^oC for commercial
(C) grade, V_BL = -24V, V_BH = -100V, -85V or -75V, V_CC = +3.3V, AGND = BGND = 0V, loop current limit =
25mA. All AC transmission parameters are specified at 600W 2-wire terminating impedance over the frequency
band of 300Hz to 3.4kHz. Protection resistors = 0W.
