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 imped-
ance circuit. 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).
