I_IH	High-level input current	V_I = 2.4 V				100	μA
I_IL	Low-level input current	V_I = 0.4 V				100	μA
I_OS	Short-circuit output current	–7 V ≤ V_O ≤ 12 V				±250	mA

(1) All typical values are at V_CC = 5 V and T_A = 25°C.

(2) The minimum V_OD specification may not fully comply with ANSI RS-485 at operating temperatures below 0°C. System designers should take the possibly lower output signal into account in determining the maximum signal-transmission distance.

(3) Δ|V_OD| and Δ|V_OC| are the changes in the steady-state magnitude of V_OD and V_OC, respectively, that occur when the input is changed from a high level to a low level.
