Notes:

1. Worst case values occur at an IC junction temperature of 150°C.

gether.

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

the logic levels of the WR and RD lines.

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.
