3Stock No. 23003-03 4/99 ES62UL256 Family NanoAmp Solutions TABLE 3: Absolute Maximum Ratings* *Stresses greater than those listed above 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 above those indicated in the operating section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. TABLE 4: Operating Characteristics (Over the Specified Temperature Range) *Notes Note 1. Operating current is a linear function of operating frequency and voltage. You may calculate operating current using the formula shown with operating frequency (f) expressed in Mhz and operating voltage (V) in volts. Example: The L device operating at 2 Mhz at 2.0 volts will draw a typical current of 0.4*2*2 = 1.6 mA. Note 2. This device assumes a standby mode if CE is disabled (high). It will also automatically go into a standby mode whenever all input signals are quiescent (not toggling) regardless of the state of CE. In order to achieve low standby current in the enabled mode (CE low), all inputs must be within 0.2 volts of either V CC or VSS.
