No. 204
The Austin Semiconductor SRAM family employs
high-speed, low-power CMOS designs using a four-transistor
memory cell. Austin Semiconductor SRAMs are fabricated
using double-layer metal, double-layer polysilicon
technology.
• Operating Temperature Ranges
Industrial (-40oC to +85oC)
Military (-55oC to +125oC)

For flexibility in high-speed memory applications, Austin
Semiconductor 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 and CE\ and OE\ go
LOW. The device offers a reduced power standby mode when
disabled. This allows system designs to achieve low standby
power requirements.
• 2V data retention/low power

*Electrical characteristics identical to those provided for the 35ns
access devices.

All devices operate from a single +5V power supply and
all inputs and outputs are fully TTL compatible.
