PCA9620

Universal LCD driver for low multiplex rates

10. Limiting values

[1]

Pass level; Human Body Model (HBM), according to Ref. 6 “JESD22-A114”.

[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 (Tamb(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

divergent conditions are described in that document.

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.

Table 34.

Limiting values

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