1.1 Maximum Ratings*

VCC and input voltages w.r.t. VSS ....... -0.6V to + 7.25V

VPP voltage w.r.t. VSS during

programming .......................................... -0.6V to +14V

Voltage on A9 w.r.t. VSS ...................... -0.6V to +13.5V

Output voltage w.r.t. VSS ................-0.6V to VCC +1.0V

Storage temperature ..........................-65°C to +150°C

Ambient temp. with power applied .....-65°C to +125°C

*Notice: Stresses above those listed under “Maximum Ratings”

may cause permanent damage to the device. This is a stress rat-

ing only and functional operation of the device at those or any

other conditions above those indicated in the operation listings of

this specification is not implied. Exposure to maximum rating con-

ditions for extended periods may affect device reliability.
