Automotive LCD driver for multiplex rates up to 1:8
11. Limiting values
CAUTION
Static voltages across the liquid crystal display can build up when the LCD supply voltage
(V_LCD) is on while the IC supply voltage (V_DD) is off, or vice versa. This may cause unwanted
display artifacts. To avoid such artifacts, V_LCD and V_DD must be applied or removed together.
Table 35. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).

[2] Pass level; Charged-Device Model (CDM), according to Ref. 7 “JESD22-C101”.
[3] Pass level; latch-up testing according to Ref. 8 “JESD78” at maximum ambient temperature (T_amb(max)).
[4] According to the NXP store and transport requirements (see Ref. 10 “NX3-00092”) the devices have to be
stored at a temperature of +8 C to +45 C and a humidity of 25 % to 75 %. For long term storage products
deviant conditions are described in that document.
