(V_CC = +3V to +5.5V, V_L = +1.8V to V_CC, T_A = -40°C to +85°C, unless otherwise noted. Typical values are V_CC = +5V, V_L = +1.8V at
T_A = +25°C.) (Notes 2, 3)

Note 2: Parameters are 100% production tested at T_A = +25°C, unless otherwise noted. Limits over temperature are guaranteed by
design.
Note 3: All currents into the device are positive. All currents out of the device are negative. All voltages are referenced to device
ground, unless otherwise noted.
Note 4: ∆V_OD and ∆V_OC are the changes in V_OD and V_OC, respectively, when the DI input changes state.
Note 5: The short-circuit output current is the peak current just prior to current limiting; the short-circuit foldback output current
applies during current limiting to allow a recovery from bus contention.
(V_CC = +5V, V_L = +5V, T_A = +25°C, unless otherwise noted.)
