Description:

The NTE2764 is a 65,536–bit (8192 X 8 bit) Ultraviolet Erasable and Electrically Programmable

Read–Only Memory (EPROM) in a 28–Lead DIP type package which operates from a single +5V sup-

ply, making it ideal for microprocessor applications. It features an output enable control and offers

a standby mode with an attendant 67% savings in power consumption.

A distinctive feature of the NTE2764 is a separate output control, output enable (OE) from the chip

enable control (CE). The OE control eliminates bus contention in multiple–bus microprocessor sys-

tems. The NTE2764 features fast, simple one–pulse programming controlled by TTL–level signals.

Total programming time for all 65,536 bits is 420 seconds.

Note 1. Exposing the device to stresses above those listed in Absolute Maximum Ratings could

cause permanent damage. The device is not meant to be operated under conditions outside

the limits described in the operational sections of this specification. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

... Function: The NTE2764 operates from a single +5V power supply, making it ideal for microprocessor applications. Programming of the NTE2764 is achieved with a single 50ms TTL pulse. Total programming time for all 65,536 bits is 420 sec. Due to the simplicity of the programming requirements, devices on boards and in systems may be easily programmed without any special programmer. ...

... 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 ...
