CAUTION

This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling

electrostatic sensitive devices.

Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A or

equivalent standards.

CAUTION

Static voltages across the liquid crystal display can build up when the LCD supply voltage

(VLCD) is on while the IC supply voltage (VDD) is off, or vice versa. This may cause unwanted

display artifacts. To avoid such artifacts, VLCD and VDD must be applied or removed together.
