ABSOLUTE MAXIMUM RATINGS
Note a: Stresses greater than 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 con-
ditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rat-
ing conditions for extended periods may affect reliability.

Note b: The STK14C88-20 requires VCC = 5.0V ± 5% supply to operate at specified speed.
Note c: ICC and ICC are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded.
Note d: ICC1 and ICC3 are the average currents required for the duration of the respective STORE cycles (tSTORE ).

Note e: E ≥2VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out.
Note f: VCC reference levels throughout this datasheet refer to VCCX if that is where the power supply connection is made, or VCAP if VCCX is con-
nected to ground.
