NTE27C25615P, NTE27C25670D  
Integrated Circuit  
256 Kbit (32Kb x 8) EPROM  
Description:  
The NTE27C256 is a 256Kbit EPROM in a 28Lead DIP type package ideally suited for microproces-  
sor systems requiring large programs and is organized as 32,768 by 8 bits. The NTE27C25612D,  
NTE27C25615D, and NTE27C25670D have a transparent lid which allows the user to expose the  
chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by follow-  
ing the programming procedure. The NTE27C25615P is suitable for applications where the content  
is programmed only one time and erasure is not required.

Note 1. Except for the rating “Operating Temperature Range”, stresses above those listed in the  
table “Absolute Maximum Ratings” may cause permanent damage to the device. These are  
stress ratings only and operation of the device at these or any other conditions above those  
indicated in the Operating sections of this specification is not implied. Exposure to Absolute  
Maximum Rating conditions for extended periods may affect device reliability.  
Note 2. Minimum DC voltage on the input or output is 0.5V with possible undershoot to 2.0V for  
a period less than 20ns. Maximum DC voltage on output is VCC +0.5V with possible over-  
shoot to VCC +2V for a period less than 20ns.
