* 310 kHz at 85°C guarantees 4800 baud; 620 kHz at 85°C guarantees 9600 baud.

This device contains circuitry to protect the

inputs against damage due to high static volt-

ages 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–impedance circuit. For

proper operation it is recommended that Vin and

Vout be constrained to the range VSS ≤ (Vin or

Vout) ≤ VDD.

Unused inputs must always be tied to an

appropriate logic voltage level (e.g., either VSS

or VDD).
