NTE2732A
Integrated Circuit
32K (4K x 8) NMOS UV Erasable PROM
Description:
The NTE2732A is a 32,768鈥揵its ultraviolet erasable and electrically programmable read鈥搊nly
memory (EPROM) organized as 4,096 words by 8 bits and manufactured using N鈥揅hannel Si鈥揋ate
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鈥揾igh signal to the CE input.
