* 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).
