Notes (apply to both driver and receiver sections):
1.
All voltages 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
DD
1,VDD2 = 5 V or VDD1= 3.3 V and TA = 25°C.
6.
7 V < V
CM < 12 V; 4.5 V < VDD < 5.5 V.
7.
Δ|V
OD| and Δ|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.
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 – tPHL| 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.
13. The relevant test and measurement methods are given in the Electromagnetic Compatibility section on p. 6.
14. External magnetic field immunity is improved by this factor if the field direction is “end-to-end” rather than to “pin-to-pin” (see diagram on p. 6).
