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 V
CC
or GND.
