Description

The TC55B8128P/J is a 1,048,576 bit high speed BICMOS static random access memory organized as 131,072 words by 8 bits

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

The TC5588128P/J features low power dissipation when the device is deselected using chip enable (CE), and has an output

enable input (OE) for fast memory access.

The TC5588128P/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 TC55B8128P/J is available in a 400mil width, 32-pin DIP and SOJ suitable for high density surface assembly.
