PCF8545

Universal LCD driver for multiplex rates up to 1:8

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.

11 Limiting values
