NOTES:
1. Change in magnitude of differential output voltage and change in magnitude of common mode output voltage are the changes in output voltage when DI input
changes state.
2. The hot swap feature disables the DE and RE inputs for the first 10μs after power is applied. Following this time period, these inputs are weakly pulled to their disabled
state (low for DE, high for RE) until the first transition, after which they become high impedance inputs.
