PCF8532

Universal LCD driver for low multiplex rates

Limiting values

[1]

Stresses above these values listed may cause permanent damage to the device.

[2]

According to the NXP store and transport conditions (document

SNW-SQ-623) the devices have to be

stored at a temperature of +5

°C to +45 °C and a humidity of 25 % to 75 %.

[3]

Pass level; Human Body Model (HBM) according to JESD22-A114.

[4]

Pass level; Machine Model (MM), according to JESD22-A115.

[5]

Pass level; Latch-up testing, according to JESD78.

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.
