NTE2764

Integrated Circuit NMOS, 64K Erasable EPROM, 200ns

NTE Electronics 

Output Deselect:

The data outputs of two or more NTE2764s may be wire–ORed together to the same data bus. In

order to prevent bus contention problems between devices, all but the selected NTE2764s should be

deselected by raising the CE input to a TTL high. OE input should be made common to all devices

and connected to the READ line from the system control BUS. These connections offer the lowest

average power consumption.
