‡

All typical values are at V

= 5 V, T = 25°C.

The algebraic convention, in which the less positive (more negative) limit is designated minimum, is used in this data sheet for common-mode

input voltage and threshold voltage levels only.

NOTE 7: This applies for both power on and power off. Refer to EIA Standard TIA/EIA-485-A for exact conditions.
