10. Pulse skew is defined as |t
11. The relevant test and measurement methods are given in the Electromagnetic Compatibility section on p. 6.
12. 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).

Skew Limit
All voltage values are with respect to network ground except differential I/O bus voltages.
Differential input/output voltage is measured at the noninverting terminal A with respect to the inverting terminal B.
Skew limit is the maximum propagation delay difference between any two devices at 25°C.
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 V
The minimum V
Δ|V
that occur when the input is changed form one logic state to the other.
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.
Includes 8 ns read enable time. Maximum propagation delay is 25 ns after read assertion.
