Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 2:
All devices are 100% production tested at T
A
= +85°C. Specifications are over -40°C to +85°C and are guaranteed by design.
Note 3:
Both receivers will operate over the ±70V input range. The input resistance increases with input voltage. The input resis-
tance will increase within 24V ≤ |V
R_IN
| ≤ 32V.
Note 4:
Guaranteed by design, not production tested.
Note 5:
Transmitter skew is measured at the transmitter zero crosspoints.
Note 6:
Output recovery time is the delayed time for the transmitter to enter normal operating mode after an overvoltage condition.
