HD66730/HD66731
Electrical Characteristics Notes
1. All voltage values are referred to GND = 0V. If the LSI is used above the absolute maximum ratings, it
may become permanently damaged. Using the LSI within the electrical characteristic is strongly
recommended to ensure normal operation. If these electrical characteristic are exceeded, the LSI may
malfunction or exhibit poor reliability.
2. V_CC ≥ V5 must be maintained. When the COM25/COMD pin is used as a extention driver interface
signal (COMD), GND ≥ V5 must be maintained.
3. For die products, specified at 75°C.
4. For die products, specified by the die shipment specification.
5. The following four circuits are I/O pin configurations except for liquid crystal display output.
