Document Title X 8 BIT LOW VOLTAGE CMOS SRAM Revision History

Initial issue Modify 28-pin DIP, SOP and TSOP packages outline dimensions. Modify 28-pin SOP and TSOP packages outline drawings and dimensions Add -LLU type Change operating voltage Vccmax from to 3.6V

Features

n External Operating Voltage: 3.6V n Access times: 55ns (max.): for VCC 3.6V 70ns (max.): for VCC 3.6V n Current: Operating: -55 series 20mA (typ.) -70 series 12mA (typ.) Standby: 1A (typ.) n Extended operating temperature range: 85 C for -LLU series n Full static operation, no clock or refreshing required n All inputs and outputs are directly TTL-compatible n Common I/O using three-state output n Data retention voltage: 2.0V (min.) n Available in 28-pin DIP, SOP and TSOP (forward and reverse type) packages

The is a low operating current 262,144-bit static random access memory organized as 32,768 words by 8 bits and operates on a low power voltage: to 3.6V. 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 at a high level, independent of the other input levels. Data retention is guaranteed at a power supply voltage as low as 2.0V.
