(1) All typical values are at 25°C and with a 3.3-V supply.
(2) VCC is 3.3 VDC ± 5%.
(3) 10% of the peak-to-peak differential output voltage swing, per TIA/EIA-485.
(4) 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 can affect device reliability. This applies to the SN65HVD30, SN65HVD31, SN65HVD33, and SN65HVD34.
