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.

14. Test information

14.1 Quality information

This product has been qualified in accordance with the Automotive Electronics Council

(AEC) standard Q100 - Failure mechanism based stress test qualification for integrated

circuits, and is suitable for use in automotive applications.
