This device contains protection circuitry to

guard against damage due to high static

voltages or electric fields. 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).
