AC Electrical Characteristics (continued)
(V₂₄ = 18V to 30V, 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: All devices are 100% production tested at T_A = +25°C. Limits over the operating temperature range are guaranteed by
design.
Note 3: Not production tested. Guaranteed by design.
Note 3: Autoretry functionality is not available in pin-mode.
