PCF8533

Universal LCD driver for low multiplex rates

The contact resistance between the SYNC pins of cascaded devices must be controlled. If

the resistance is too high then the device will not be able to synchronize properly. This is

particularly applicable to COG applications. Table 19 shows the limiting values for contact

resistance.
