All typical values are at VCC = 5 V and TA = 25°C.
The algebraic convention, where the less positive (more negative) limit is designated as minimum, is used in this data sheet for common-mode
output and threshold voltage levels only.
NOTES:
6. Not more than one output should be shorted at a time, and the duration of the short circuit should not exceed one second.
7. Refer to ANSI Standards TIA/EIA-422-B, TIA/EIA-423-A, and TIA/EIA-485-A for exact conditions.
