Features

Single + 5V power supply

Access times: 10/12/15 ns (max.)

Current: Operating: 150mA (max.)

Standby:

12mA (max.)

Full static operation, no clock or refreshing required

All inputs and outputs are directly TTL compatible

Common I/O using three-state output

Data retention voltage: 3V (min.)

Available in 32-pin SOJ and TSOP packages

General Description

The A617308 is a high-speed, low-power 1,048,576-bit
static random access memory organized as 131,072
words by 8 bits and operates on a single 5V power
supply. It is built using high performance CMOS process.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.

Minimum standby power is drawn by this device when
chip enable is disable, independent of the other input
levels.
Data retention is guaranteed at a power supply voltage
as low as 3V.
