(1) Unless otherwise specified min/max limits apply across the 0°C to +70°C range for the DS96172/DS96174. 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 EIA Standards RS-422A and RS-485, V_OC, which is the average of the two output voltages with respect to ground, is called output
offset voltage, V_OS.
(5) Only one output at a time should be shorted.
