Note 2: All devices are 100% production tested at TA = +85°C. All temperature limits are guaranteed by design.
Note 3: A transmitter/receiver edge is defined as a transition through the transmitter/receiver input-logic thresholds.
Note 4: Transmitter skew is measured at the transmitter zero cross points.
