The power-off measurement in TIA/EIA-422-B applies to disabled outputs only and is not applied to combined inputs and outputs.
All typical values are at VCC = 5 V and TA = 25
°
C.
§The minimum VOD2 with a 100-
load is either 1/2 VOD1 or 2 V, whichever is greater.
|VOD| and
|VOC| are the changes in magnitude of VOD and VOC, respectively, that occur when the input is changed from one logic state to
the other.
#Duration of the short circuit should not exceed one second for this test.
NOTE 4: This applies for both power on and power off; refer to TIA/EIA-485-A for exact conditions. The TIA/EIA-422-B limit does not apply for
a combined driver and receiver terminal.
