DC Electrical Characteristics (continued)
(V₂₄ = 9V to 60V, V5 = 4.5V to 5.5V, VL = 2.5V to 5.5V, V_GND = 0V; REG unconnected, all logic inputs at V_L or GND; T_A = -40°C to
+125°C, unless otherwise noted. Typical values are at V₂₄ = 24V, V5 = 5V, VL = 3.3V, and T_A = +25°C, unless otherwise noted.) (Note 2)
