This device contains circuitry to protect the
inputs against damage due to high static
voltages or electric fields; however, it is ad-
vised that normal precautions be taken to avoid
application of any voltage higher than maxi-
mum rated voltages to these high impedance
circuits.
This CMOS memory circuit has been de-
signed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established. The circuit is in a test
socket or mounted on a printed circuit board
and transverse air flow of at least 500 linear
feet per minute is maintained.
