(1) Unless otherwise specified min/max limits apply across the −55°C to +125°C temperature range for the DS16F95 and across the 0°C to
+70°C range for the DS36F95. All typicals are given for V_CC = 5V and T_A = 25°C.
(2) All currents into the device pins are positive; all currents out of the device pins are negative. All voltages are referenced to ground
unless otherwise specified.
(3) Δ|V_OD| and Δ|V_OC| are the changes in magnitude of V_OD and V_OC, respectively, that occur when the input is changed from a high level
to a low level.
(4) In TIA/EIA-422A and TIA/EIA-485 Standards, V_OC, which is the average of the two output voltages with respect to ground, is called
output offset voltage, V_OS.
(5) Refer to TIA/EIA-485 Standard for exact conditions.
(6) Only one output at a time should be shorted.
