DESCRIPTION

The ISSI IS61LV2568 is a very high-speed, low power, 262,144-word by 8-bit CMOS static RAM. The IS61LV2568 is fabricated using ISSIs high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields higher performance and low power consumption devices.

When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down to 36mW (max.) with CMOS input levels. The IS61LV2568 operates from a single 3.3V power supply and all inputs are TTL-compatible.

The IS61LV2568 is available in 36-pin 400-mil SOJ, and 44-pin TSOP (Type II) packages.
