However, precau- tions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high–impedance circuit. For proper opera- tion, it is recommended that the voltage 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 (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 an appropriate logic voltage level (e.g., GND or VCC for DI, and GND for Rx). |
