For proper operation, it is recom- mended that the voltages at the DI and DO pins be constrained to the range GND VDI VCC and GND VDO ≤ VCC. Also, the voltage at the Rx pin should be constrained to (VSS – 15 V) ≤ VRx1 – Rx3 (VDD + 15 V), and Tx should be constrained to VSS VTx1 – Tx3 VDD. Unused inputs must always be tied to appropriate logic voltage level (e.g., GND or VCC for DI, and GND for Rx). |
