Revision History
• Table: ICC3 Operating Current (READ) change on test condition section as follows:
OLD: C = 0.1VCC / 0.9VCC at 25 MHz, Q = open; NEW: C = 0.1VCC / 0.9VCC at 25 MHz
and 75 MHz, Q = open; OLD: C = 0.1VCC / 0.9VCC at 20 MHz, Q = open; NEW: C =
0.1VCC / 0.9VCC at 20 MHz and 33 MHz, Q = open.
