Stock No. 23087-01 12/98 3 EM033C08 NanoAmp Solutions TABLE 3: Operating Characteristics (Over specified temperature range) Notes: Note 1. Operating current is a linear function of 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: Operating at 2 Mhz and 2.0 volts will draw a maximum current of 0.3*2*2 = 1.2 mA. Note 2. This device assumes a standby mode whenever Chip Enable (CE ) is disabled (high). It will also automatically go into a standby mode whenever all input signals are quiescent (not toggling) whenever an access or write cycle is completed regardless of the state CE. In order to achieve low standby current all input levels must be within 0.2 volts of either VCC or GND.
