E2 is of opposite polarity to E1. 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 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. |
