Note 2:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
Note 3:
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.
Note 4:
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.
Note 5:
∆
|V
OD
| and
∆|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.
Note 6:
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
.
Note 7:
Only one output at a time should be shorted.
