Universal LCD driver for low multiplex rates
13. Application information
13.1 Multiple chip operation
For large display configurations or for more segments (> 128 elements) to drive please
refer to the PCF8576D device.
The contact resistance between the SYNC input/output on each cascaded device must be
controlled. If the resistance is too high, the device will not be able to synchronize properly;
this is particularly applicable to chip-on-glass applications. The maximum SYNC contact
resistance allowed for the number of devices in cascade is given in Table 19.
