Note 1: If the RS-485 transmission lines are unterminated and a short to a voltage V_SHT occurs at a remote point on the line, an active
local driver (with DI switching) may see higher voltage than V_SHT due to inductive kickback at the driver. Terminating the line
with a resistor equal to its characteristic impedance minimizes this kickback effect.
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.
ELECTRICAL CHARACTERISTICS
(V_CC = +3.0 to +5.5V, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at V_CC = +3.3V and T_A = +25°C.) (Notes 2, 3)
