Static design eliminates the need for external clocks or timing strobes while CMOS circuitry reduces power consumption and provides for greater reliability. For flexibility in high-speed memory applications, ASI offers chip enable (CE\) and output enable (OE\) capability. These enhancements can place the outputs in High-Z for additional flexibility in system design. Writing to these devices is accomplished when write enable (WE|) and CE\ inputs are both LOW. Reading is accomplished when WE\ remains HIGH while CE\ and OE\ go LOW. The devices offer a reduced power standby mode when disabled. This allows system designs to achieve low standby power requirements. The “L” version provides an approximate 50 percent reduction in CMOS standby current (ISBC2) over the standard version. All devices operation from a single +5V power supply and all inputs and outputs are fully TTL compatible. L *Electrical characteristics identical to those provided for the 45ns access devices.
