This device contains circuitry to protect the
inputs and outputs against damage due to high
static voltages or electric fields; however, it is
advised that normal precautions be taken to
avoid applications of any voltage higher than
maximum rated voltages to this high imped-
ance circuit.
For proper operation it is recommended that
Vout and Vin be constrained to the ranges
described as follows:
Digital I/O: Driver Inputs (DI):
(GND
≤
VDI
≤
VCC).
Receiver Outputs (DO):
(GND
≤
VDO
≤
VCC).
EIA–232 I/O: Driver Outputs (Tx):
(VSS
≤
VTx1 – Txn
≤
VDD).
Receiver Inputs (Rx):
VSS – 15 V
≤
VRx1 – Rxn
≤
VDD
+ 15 V).
Reliability of operation is enhanced if unused
outputs are tied off to an appropriate logic
voltage level (e.g., either GND or VCC for DI,
and GND for Rx).
