(1) All typical values are at 25°C and with a 5-V supply.

(2) 10% of the peak-to-peak differential output voltage swing, per TIA/EIA-485

(3) Under some conditions of short-circuit to negative voltages, output currents exceeding the ANSI TIA/EIA-485-A maximum current of 250 mA may occur. Continuous exposure may affect device reliability.
