The power-off measurement in ANSI Standard EIA/TIA-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 a high level to a
low level.
NOTE 3: This applies for both power on and off; refer to EIA Standard RS-485 for exact conditions. The EIA/TIA-422-B limit does not apply for
a combined driver and receiver terminal.
