† The power-off measurement in ANSI Standard 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.
§
∆|V
OD| and
∆|V
OC| 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.
¶ The minimum VOD2 with a 100-Ω load is either 1/2 VOD1 or 2 V, whichever is greater.
NOTES: 5. See ANSI Standard TIA/EIA-485-A, Figure 3.5, Test Termination Measurement 2.
6. This applies for both power on and off; refer to ANSI Standard TIA/EIA-485-A for exact conditions. The TIA/EIA-422-B limit does
not apply for a combined driver and receiver terminal.
