(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 VCC

= 5V and TA = 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 |VOD| and Δ|VOC| are the changes in magnitude of VOD and VOC 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, VOC, which is the average of the two output voltages with respect to ground, is called output

offset voltage, VOS.

(5)

Only one output at a time should be shorted.
