Current Loop Protector
DC ELECTRICAL CHARACTERISTICS (continued)
(I_IN = 50FA to 24mA, T_A = -40NC to +85NC, R_LOAD = 25I to 1kI, unless otherwise noted. Typical values are at I_IN = 10mA, R_LOAD
= 250I, and T_A = +25NC.) (Note 2)

Note 2: All devices are 100% production tested at T_A = +25NC, unless otherwise noted. Limits over the -40NC to +85NC operating
temperature range are guaranteed by design.
Note 3: Turn-on time and turn-off time are defined as the difference in the time between when the output voltage crosses 10% and
90% of the final output voltage.
Note 4: Input current source can support voltage up to +40V (absolute maximum). Current reaction time is defined as the settling
time of the output current after a fault event.
Typical Operating Characteristics
(V_IN = 24V, I_IN = 10mA, R_LOAD = 250I, unless otherwise noted. Typical values are at T_A = +25NC.)
