Note 1

Absolute Maximum Ratings are those values beyond which damage to the device may occur All voltages referenced to ground unless otherwise noted

Note 2

The DB0–DB3 and AD0–AD3 lines all have active P-channel pull-up transistors which will source current The CS RD and WR lines have internal pull-up
