描述 Description

The TC5589P/J is a 73,728 bit high speed CMOS static random access memory organized as 8,192 words by 9 bits and operated

from a single 5V supply. Toshiba's advanced CMOS technology and circuit design enable high speed operation.

The TC5589P/J features low power dissipation when the device is deselected using chip enable (CE1, CE2) and has an output

enable input (OE) for fast memory access. Also, the device power between memory accesses is reduced by an automatic power

down circuit.

The TC5589P/J is suitable for use in high speed applications such as cache memory and high speed storage. All inputs and

outputs are TTL compatible.

The TC5589P/J is available in a 300mil width, 28-pin DIP and SOJ suitable for high density surface assembly.
