Note 1: During normal operation, a termination resistor must be connected between A and B in order to guarantee overvoltage pro-
tection up to the absolute maximum rating of this device. When not in operation, these devices can withstand fault voltages
up to the maximum rating without a termination resistor and will not be damaged.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
DC ELECTRICAL CHARACTERISTICS
(V_CC = +4.75V to +5.25V, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at V_CC = +5V and T_A = +25°C.)
