Absolute maximum ratings*  
*NOTICE: Stresses beyond those listed under “Absolute maximum  
ratings” may cause permanent damage to the device. This  
is a stress rating only, and functional operation of the  
device at these or any other conditions beyond those  
indicated in the operational sections of this specification is  
not implied. Exposure to absolute maximum rating

Notes: 1. X can be VIL or VIH.  
2. Refer to the programming characteristics.  
3. VH = 12.0 0.5V.  
4. Two identifier words may be selected. All Ai inputs are held low (VIL), except A9, which is set to VH, and A0, which is tog-  
gled low (VIL) to select the manufacturer’s identification word and high (VIH) to select the device code word.  
5. Standby VCC current (ISB) is specified with VPP = VCC. VCC > VPP will cause a slight increase in ISB.
