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.
NOTE:
1.
θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
Electrical Specifications
Unless Otherwise Specified, TA = -40oC to 85oC, VBL = -24V, VBH = -100V, VCC = +5V, AGND = BGND = 0V,
loop current limit = 25mA. All AC Parameters are specified at 600
, 2-wire terminating impedance over the
