Notes:
1. Worst case values occur at an IC junction temperature of 150°C.
2. For designers who do not need to read from the display, the Read line can be tied to V
3. Changing the logic levels of the Address lines when CE = “0” may cause erroneous data to be entered into the Character RAM, regardless of
4. The display must not be accessed until after 3 clock pulses (110 μs min. using the internal refresh clock) after the rising edge of the reset line.
