Limiting values

[1]

Derate by 7.7 mW/K when Tamb >60 C.

[2]

Pass level; Human Body Model (HBM), according to Ref. 7 “JESD22-A114”.

[3]

Pass level; latch-up testing according to Ref. 8 “JESD78” at maximum ambient temperature (Tamb(max)).

[4]

According to the store and transport requirements (see Ref. 13 “UM10569”) the devices have to be stored at a temperature of +8

C to

+45

C and a humidity of 25 % to 75 %.

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.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134).
