NOTES:
1. Junction temperature is a function of on–chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient
temperature, air flow, power dissipation of other components on the board, and board thermal resistance.
2. Per SEMI G38–87.
3. Measured using a four–layer test board with two internal planes.
4. Indicates the average thermal resistance between the die and the printed circuit board as measured by the ring cold plate method.
5. Indicates the average thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC–883
Method 1012.1).

This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised that
normal precautions be taken to avoid applica-
tion of any voltage higher than maximum rated
voltages to this high–impedance circuit.
This CMOS memory circuit has been
designed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established.
This device contains circuitry that will ensure
the output devices are in High–Z at power up.
