Stresses greater than those listed under Absolute Maxi-
mum Ratings may cause permanent damage to the de-
vice. This is a stress rating only; operation of the device at
any condition above those indicated in the operational
sections of these specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods
may affect device reliability.
STANDARD TEST CONDITIONS
The DC Characteristics and capacitance sections below
apply for the following standard test conditions, unless
otherwise noted. All voltages are referenced to GND (0V).
Positive current flows into the referenced pin (Test Load).
Available operating temperature range is:
S=0°C to 70°C

All AC parameters assume a load capacitance of 50 pF.
Add 10 ns delay for each 50 pF increase in load up to a
maximum of 150 pF for the data bus and 100 pF for
address and control lines. AC timing measurements are
referenced to 1.5 volts (except for clock, which is refer-
enced to the 10% and 90% points). Maximum capacitive
load for PHI is 125 pF.
