GENERAL DESCRIPTION
The Austin Semiconductor SRAM family employs
high-speed, low power CMOS designs fabricated using doublelayer metal, double-layer polysilicon technology.
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.
All devices operation from a single +5V power supply
and all inputs and outputs are fully TTL compatible.
• Operating Temperature Ranges

Industrial (-40oC to +85oC)
