NOTE: This device contains protection circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is
advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit.
For proper operation, it is recommended that the voltages at the DI and DO pins be constrained to the range GND < VDI < VDD and GND < VDO
< VCC. Also, the voltage at the RX pin should be constrained to +25V, and TX should be constrained to VSS < VTX1-3 < VDD. Unused inputs
must always be tied to an appropriate logic voltage level (e.g., GND or VCC for DI, and VSS or VDD for RX).
DC ELECTRICAL CHARACTERISTICS
Typical values are at TA = 0 to 70°C; GND = 0V, unless otherwise specified.
