NTE2732A
Integrated Circuit
32K (4K x 8) NMOS UV Erasable PROM
Description:
The NTE2732A is a 32,768–bits ultraviolet erasable and electrically programmable read–only
memory (EPROM) organized as 4,096 words by 8 bits and manufactured using N–Channel Si–Gate
MOS processing. With its single +5V power supply and with an access time of 200ns, the NTE2732A
is ideal for use with high performance +5V microprocessors such as the NTE3880.
The NTE2732A has an important feature which is the separate output control, Output Enable (OE)
from the Chip Enable control (CE). The OE control eliminates bus contention in multiple bus micropro-
cessor systems.
The NTE2732A also features an standby mode which reduces the power dissipation without increas-
ing access time. The active current is 125mA while the maximum standby mode is achieved by apply-
ing a TTL–high signal to the CE input.

Note 1. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. This is a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the operational sections of this specifi-
cation is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
