Notes: These apply to both driver and receiver sections
1. All Voltage values are with respect to network ground except differential I/O bus voltages.
2. Differential input/output voltage is measured at the noninverting terminal A with respect to the inverting terminal B.
3. Skew limit is the maximum propagation delay difference between any two devices at 25°C.
4. 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.
5. All typical values are at V_DD1,V_DD2 = 5 V or V_DD1= 3.3 V and T_A = 25°C.
6. While –7 V<V_CM>12 V, the minimum V_OD2 with a 54 Ω load is either ½ V_OD1 or 2.3 V, whichever is greater.
7. ∆|V_OD| and ∆ |V_OC| are the changes in magnitude of V_OD and V_OC, respectively, that occur when the input is changed form one logic state to
the other.
8. This applies for both power on and power off, refer to ANSI standard RS-485 for exact condition. The EIA/TIA-422-B limit does not apply
for a combined driver and receiver terminal.
9. Includes 10 ns read enable time. Maximum propagation delay is 25 ns after read assertion.
10. Pulse skew is defined as the |t_PLH –t_PHL| of each channel.
11. Absolute Maximum specifications mean the device will not be damaged if operated under these conditions. It does not guarantee
performance.
