40 °C to +125 °C.
* The input levels and difference voltage provide zero noise immunity and should be tested only in a static, noise-free environment.
Outputs of unused receivers assume a logic 1 level when the inputs are left open. (It is recommended that all unused positive inputs
be tied to the positive power supply. No external series resistor is required.)
Test must be performed one lead at a time to prevent damage to the device.
