This device contains protection circuitry to pro-

tect the inputs against damage due to high static

voltages or electric fields; however, it is advised

that normal precautions be taken to avoid applica-

tion 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≤ VCC and GND≤ VDO ≤ VCC. Also, the

voltage at the Rx pin should be constrained to

(VSS – 15 V) ≤ VRx1–3 ≤ (VDD + 15 V), and Tx

should be constrained to VSS ≤ VTx1–3 ≤ VDD.

Unused inputs must always be tied to an ap-

propriate logic voltage level (e.g., GND or VCC for

DI and Ground for Rx.)
