Notes (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 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. −7 V < V_CM < 12 V; 4.5 V < V_DD < 5.5 V.
7. Δ|V_OD| and Δ|V_OC| are the changes in magnitude of V_OD and V_OC, respectively, that occur when the input is changed from 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 |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.
12. Differential output voltage is measured at terminal Y with respect to Z.
