(5) Cautions related to serial data transfer
1. To ensure that the high-frequency digital signals transferred to the CL, DI, and CE pins do not spill over to the
analog signal block, either guard these signal lines with a ground pattern, or perform transmission using shielded
wires.
2. The data format of the LC75412E and 75412W uses 8-bit addresses and 44-bit data. When sending data using
multiples of 8 (when sending 48 bits), use the method described in Figure 1.

(6) Note on usage of external muting
When using external mute function, take adequate countermeasures against noise to prevent malfunction.
