Notes: 1. X can be VIL or VIH.
2. Read, output disable, and standby modes require, 3.0V ≤VCC ≤3.6V, or 4.5V ≤VCC ≤5.5V.
3. Refer to Programming Characteristics. Programming modes require VCC = 6.5V.
4. VH = 12.0 ± 0.5V.
5. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled
low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.
